Useful feedback, thanks Linnea. I've turned down the volume for my next video (due to be published in the next couple of days), so please let me know if that works better :-)
My Electrophysiologist accepted the downloaded ECG from my Samsung Galaxy 4 as evidence that his first attempt at catheter ablation for my atrial fibrillation had failed. Happily, Round Two worked, and my Galaxy watch shows NSR routinely.
Man my first catheter ablation failed and not only that i was seconds from death . I am trying to find a watch to scan my heart and i really dont know wich .
@@padila176 sorry to hear that hope your doing well. I had two ablation(One for AFIB and second one for atrial flutter)and Im using a apple watch 9 series and not sure how accurate these graphs are. With ablation one needs to find the best doctor who are good at doing ablations.
My daughter's apple smart watch helped in detecting my husband was in the middle of a heart attack. From what she saw, we went to the hospital & he got a stint. His symptoms were only sweating & nausea. No chest pain until well after getting to the ER. Thankful she was nearby with her watch & we were just a few blocks from the hospital.
Nice video. This was the first video that came up when I searched. I say that because I'd recommend turning down the music a tad bit in the future, it's a slight bit distracting. Thanks for the video though.
Good to see doctors involving themselves in this ongoing conversation. Hopefully it will lead to more useful data to be collected in the long term and a better general awareness of what these measurements actually mean for one's health.
Interesting, so my current Apple Watch with ECG could do a 6 lead reading just by me using it on different parts of my body. I have SVT and am worried it may mean to something else so this is useful to know thanks.
What an amazingly helpful video. My fitbit versa showed irregular heart rthym. My Dr confirmed this with an eg 24 hrs test. I had no symptoms so wouldn't have known I have atrial flutter.😮
And that is its real value. Having a device on with multiple uses like a watch that also keeps a eye on some vitals. It's not perfect but getting better but any 'hints' something is up is better than no hints at all. Over the last few years way more afib has been detected and people can act. The downsides is these more cases of detected afib are also being used in many conspiracies plots...
Had a silent heart attack 2 weeks ago. My only symptom was sudden shortness of breath. I did use my Samsung Galaxy Watch4 to run an ECG on 7th Sep and another one on 11th Sep. Both tests were "inconclusive" and the waves were irregular but the watch prompted me to seek medical attention if the same results get repeated. So, I would believe that while these smartwatches do not explicitly check for heart attack (for one reason or another), they are smart enough to recognise a potential issue and alert you to take action about it.
I have hashimotos and have had all kinds of autoimmune health issues the last few years, I wasn't feeling good at all at work one day, hand tremors, sweats, felt super weak etc, used the ECG on my watch and it said atrial fibrillation was detected, it subsided and I went in to the walk in to get it checked out when it started again showed the doc the watch's data and explained everything that happened then and what was currently happening at the time of going in and she sent me to the ER. The ER docs dismissed any of that info and even though my thyroid levels were good, talked about upping my dosage... So if I'm already having arrythmias and the like I don't see what compels them to want to up my dosage even though they even said the levels were good but of course this is hashimotos and as far as I know at any moment I could be flooded with thyroid hormone at any moment while still taking the daily doses of levothyroxine.
My galaxy 6 watch detected atrial fibrillation multiple times after going for 3-5 km runs. I only experience discomfort after strenuous exercise. Ive had to wear holter monitors that detected no abnormalities. The problem is that i only experience irregular heart rythm after exercise
Thank you so much for this video, a rare insight on this important subject. Your channel has an obvious potential and I am confident it will be soon with thousands of subscribers. Working for the NHS, and being a GP, while still having the time to offer this channel to us is nothing short of a miracle of social work. Thank you, Tom.
Hi Doc. Can you give me some advice. I have a fast heart rate even if Im in rest. My doctor also stops me from drinking coffee and everything that can cause palpitation. Doctors already perform ECG, Xray and even blood tests. And all the test was normal. But eventually I'm still suffering from palpitation, the suddenly my hands and face become numb and my vision get blurry. Can you tell me Doc what is the problem.
I keep getting a strange feeling in my chest when I do my watch says atrial fibrillation detected speak to your gp well been to the doc as I keep getting tachycardia and blood pressure keeps going up but it was all within normal range but at the higher end when I was there had an ecg it was normal I asked for a 24hour ecg and i was refused
Please, I want to inquire about the ECG app. It worked with me for two days from the purchase of the watch (version 9), but now it has not sent updates or the PDF file on my iPhone I don’t know why, the update shows on the watch only, but on my iPhone(15 pro max), there is no notification or anything, and the last updated on 2 Feb 2024
Hi, nice video..u got me interested in knowing more. I had AFib and done my ablation about 6 years ago and last year i hve VPC in which am on medication now. Will a smartwatch be a useful for me. Its an expensive item. Am 55 this month. Tq
I think it would be interesting if you watch could identify lethal arrhythmias such as ventricular tachycardia and ventricular fibrillation, contact 911 and give your location as well as your condition, sound an audible alarm and then flash on screen to start CPR. With the Apple Watch that is capable of making phone calls, if it automatically called 911, the operator could give instructions to someone who is not trained to do CPR.
Actually JUST NOW, DURING THIS VIDEO pretty obviously re-locked into a sinus rhythm and came out of an afib episode, and both a Kardiacare and Garmin watch apparently verified the huge, off-the-cliff drop in heart beat rate which was also then backed up with the ekg results. Will still be going to my cardiologist appointment set up after I recognized the symptoms days ago, but the relief is amazing. I am perfectly happy with the diagnostic capabilities, but better is always appreciated. Now I can get back on my cycling training.
I have afib and a lot of pvc and pac. Will these watches pick up these abnormalities also? My Kardia does most of the time, but not always the most convenient to use.
Same for me, I wish someone would answer your question. After multiple heart monitors snd using Kardia app, I'm considering buying the Apple watch. But hate to spend the money if it wouldn't be accurate. I have SVT, PAC and PVC's. Recently, I was out without my Kardia device and believe I had an AFib episode.
It would be interesting if you could compare the Apple Watch ECG results with a Fitbit Charge 5 (or another Fitbit ECG enabled band) and a Kardia 6-lead device. To me, it doesn’t seem to make a difference which one you use, as they only look at the basic rhythm rather than analysing everything and taking a holistic view. But perhaps I’m wrong, it would be great to get your perspective.
I was sitting at home a few days ago, and my heart started feeling weird, I started an ecg on my Apple Watch and it showed atrial fibrillation, it’s never shown this before, I’ve got an appointment anyway for blood pressure review on 31st Jan, so I’ll mention it then.
@@Chris34720 everything has been fine, I spoke to them when I was at the docs for my bp review, hasn’t happened since, but it’s been noted in my notes ☺️
Not sure what happened but owing a blood pressure meter is always good and most good ones (say in $50 range) also do afib detect so you can keep a eye on both.
Hi I have SVT and would like your advice on best smart watch that has the most accurate ECG and also tracks your heart 24/7 continuously. Many thanks ❤
I regularly take my ECG on my galaxy 5, always fine, but i got one reading saying it found signs of artial fibrillation when i was hungover. Should that be a concren?
Not a doctor here but a patient with lots of patient experience. Afib is very common and not necessaryily dangerous. If your total time in Afib is only a few minutes a year and when you have been drinking a lot of alcohol, you can just cut down on the drinking trigger mechanism and not worry. Also, a lot of aberrant readings on ECGs and smart devices tend to be captured as Afib. I once had a bad ECG reading in a doctor's office that said I had a Myocardial Infarction when I was highly fit and 38. There was nothing wrong with me.
How about the latest models? Fitbit has fb sense 2, theres also apple watch 8 and galaxy watch 5 now. I do have irregular heart rhythm and I do want something that's accurate. Which one do you recommend?
I couldn't find any published research that specifically mentions these devices. Its a big issue in the industry - knowing yesterday's model and algorithm are accurate is one thing, but what about newer versions? It's why the comparison study I reference is pretty big news in this space (albeit using older models). If you put a gun to my head though, I'd probably lean towards the Apple Watch 8. That's because looking at older models, Apple seem to have developed an accurate algorithm for detection of irregular heart rhythms that is always amongst the best. In addition to this, there are more journal publications on the use of Apple Watches for a variety of medical use cases that for the others. This doesn't neccessarily mean its better - but it means that if we discover more uses for this kind of technology, its more likely we'll find them for the Apple Watch before the others, if this trend continues.
@Mickle Doc Hey thanks so much for the reply! Really appreciate it. Awesome video too btw! Thanks for sharing your recommendation. I started following development updates for wearables with ecg 2 years ago when I found out I had some form of tachycardia... honestly was hoping to hear more praises towards the cheaper models as I'm not an iphone user (plus apple watch is more expensive than the rest) and the watch is unusable without an iphone. But yeah, at the back of my head, I do think joining the dark side might be a better investment health-wise. And I've been postponing this decision for way too long. Anyway, thanks so much for your insights! P.s. My cardiologist specifically recommended only the apple watch (q2 2021 so maybe series 5/6) and I kinda thought he was just an apple fanboy
@@crazybits9257 This is also the reason I'm considering an apple watch 8, even though I don't even have an iPhone. There is another youtube channel called the quantified scientist who uses real world data to compare health trackers (ruclips.net/video/YVhmzxpw5Gg/видео.html) and he also found that Apple watches are the most accurate.
Fitbit Charge 5 is now owner by Google and will require Google account. May not matter to you where your data is stored but users who dont want to give Google their fitness data will lose al their data. Just thought I'd share.
You would rather have a false positive and test using the ECG function and when still in doubt goto the hospital to get a ecg than not detecting at all. Also not sure why he uses such old models even when making this video apple for example had already supported this for 3 years (first watch todo this was model 7 released a full 2 years before the video). For me apple watch 7 and new models have never detected a afib when it was not happening also in background mode. Detecting as a 'signal' so we can test is always 100% better than not knowing at all. Its like saying lets not put seatbelts on because some people still get killed.
Thank you for the vid. I am still not sure if a watch is right for me. Can you do a vid about the Kardia mobile? Please allow me to share an other comment, not to be rude or anything, but please consider lowering the volume of the background music in future vids (or not using it at all), greetings
Great suggestion @kingraw2000! I'll line up Kardia Mobile for a future review. And apologies about the background music - I've had similar feedback from a few viewers, so hopefully you'll see (or hear!) and improvement in future vids. Thanks for your support!
Your chart says that Kardia mobile is less accurate than Apple Watch 6. Have both. The Kardia takes a three point reading and shows six leads in the graph. My cardiologist says the Kardia gives more information, but neither the Kardia nor the watch are really useful in his opinion with the Kardia being somewhat more useful than the watch. He would prefer that I wear a device continuously, which is embedded under my skin. That doesn’t sound comfortable.
I will do, thanks for the tip. I used to use a MyZone chest strap for heart rate monitoring too - it was consistently more accurate than my wrist-based wearables, so I tended to use it alongside my Smart Watch when exercising. Makes sense that the same principle would apply for ECG monitoring
@@MickleDoc I've been using it for heart issues and it's a lifesaver and the people running it are also very helpful. The device will record a single source ECG (lead 5?) for up to 24 hours, it is synced to the cloud and the link can then be sent directly to the cardiologist. Real-time ECG's can also be monitored. The cost might seem high but it is less than the private cost of a 3 day Holter monitor. It is being sold as a fitness device but it's real benefit is for people like myself.
In the UK, there is plenty we might still offer someone with intermittent AFib depending on their other risk factors. I would recommend that anyone who thinks they may have intermittent AFib speak with their medical team.
@@ml3141 I'm going through this right now. Options are: 1). Do nothing as Afib is not necessarily dangerous in and of itself but could be if you have other factors. 2). If you have a sustained Afib episode you can have it cardioverted to sinus rhythm either electrically or with a drug -- under medical supervision usually at an ER. This ends the episode but many times it returns (but not always). 3). You can take a rate control medication like a beta blocker if you Afib is the type with a high heart rate. And also take an anti-arrhythmic drug like digoxin or flecainide to reduce the arrythmia. These would be all the time. Drugs have side effects. 4). You could practice "pill in the pocket" strategy which is to take the prescribed rate control and anti-arrhythmic drugs as needed however this is a decision that mut be made in close consult with the medical team base don your risk factors and other drugs. 5). You can get an ablation that is an invasive but usually safe surgery where the doctor freezes or cuts the nerve on your heart that is sending the bothersome signals. Sometimes it works, sometimes it needs subsequent procedures. Of course risk is always present in procedures. 6). There is a new device called a Watchman that prevents clots that are the most dangerous possible effect of Afib. I am not a doctor but a new Afib patient and am considering options so just sharing.
You have a better chance of catching it with multiple smart watch readings than a single ecg from the doctor. You usually wear a 24 hour Holter monitor to catch it, since most arrhythmias aren't constant.
@@bobozwald3234 Or daily both tools have its value but they better tool can only detect it when its attached the power of watch versions you can have them on 23.5+ hours a day all year.
Just found your channel and subscribed. Been having lots of problems getting my health professionals to take my b12 deficiency seriously. Despite producing multiple evidence that it improves my long covid symptoms I can’t get them to increase them to more than monthly. The ignorance of the NICE guidelines and the benefits of b12 injections for particular Patients is frightening.
In many cases, after about a year the watch can't read the ECG any more. Don't buy it if the ECG functions. That happened to my watch, funny just after the warranty expired.
Back In August of this year I had a stoke due to a AFIB. I am 47 years old. I weight 205 pounds 6 ft. I am in good health or thought I was. I picked up a samsung watch to monitor myself. This was after I had to ware a monitor for 2 weeks after leaving the hospital. I am not sure if this works accurately or not but I now have a eye out on my heart rhythm now. It is scary and I did sneak up in me. I suggest everyone should just be aware of this. 4 months later and I am back to 80% on my right side. I do experience brain fog from time to time. Everyone should get a smart device it could save them.
That was great, Tom. Like many runners I wear a Garmin forerunner watch that has a heart rate monitor. That feeds into zones in Strava. My issue with that is it assumes a standard calculation to work out the maximum heart rate - 220 minus age. Based on that I should be dead, so as a keen athlete how can I work out what the correct heart rate zones should be?
Unfortunatley, there's no great solution to this. Several different formulas have been developed (the one you refer to is the Fox Formula, but there are others, like the Tanaka formula) but they all fall foul of over or under estimates. You might be best using a heart monitor (chest straps more accurate that wrist watches) and matching HR with your self-perceived exercise intensity, in order to map out your own, personalised heart rate zones.
Good question. It's because independent research comparing wearables is rare! This was the best research paper I could find on the subject with multiple participants (rather than just one person's review). Hopefully it still gives an idea of how the different algorithms can vary and that for some companies, the reality doesn't always match the marketing!
Hello! Dc Tom, the video is helpful but I just have a little question, would be able to tell me how accurate(ECG) is on apple smart watch series 8 which there are the latest versions with the latest versions of software Thanks
Hi, great question. I've just had a look though and I'm afraid I can't find any publicly-available research specifically on the series 8. Apple doesn't tend to post research on their website and I can't see any published papers on the online research database I use. I'll keep a look out though!
If a patient had a history of ECG irregularities, it could be possible to install micro transmitters, on or in the thoracic cavity, to give true multi-channel ECG.
Yes he used a very old model (6) by the time the video was released we already had this background mode for about 2 years. While a useful video its a pity he talks about progress in the field but also used such a old model even a year ago.
Why use such old data? talking about the apple watch 6. The apple watch 7 and 8 where already released and also detected afib for example. My apple watch 7 picked up my afib during the day and started giving warnings >2.5 years ago. So it also supported the '24h detect mode'. I am not saying this video is not interesting but time has moved on we are close to the release of apple watch 10 already. Also while its true we have not seen how much/often it misses afib we do know its way way way more than not having any way to detect them 24h/day or even using the ECG if you feel weird. I always send my ecg to the hospital and they can work with this if anything new is happening they will call me in for the 'many wires one' to confirm a change. Its a great 'easy to have on' tool to keep track of things even if its not proof of anything at 100%. Its conclusion should be is it a 'confident hint' that can be used to talk to someone or go in for a test is a clear yes and thats is so much more than we had before.
There is a new watch called Cardiac Sense and it’s Israel technology and supposed to be very very accurate. But it’s expensive. Do you have any idea about this as I have MVP and AFib and I am told by my cardiologist to wear one?
Sorry Doc, but we don't need an ECG on the wrist. First, no one other than a trained professional can read and interpret such a chart. What we - really - need is a big red Engine Check light on the wrist.
A trained profession can only look at it if he well looks. Software might not be 100% correct and as pointed out only has 1 datapoint but its better than not having ANY hints at all. Its like not having any engine lights and just waiting for the car to stop and yell 'clearly something is wrong now'. Also second remark is kind of silly a modern watch can now check 4 or 5 vitals making it very much like a engine check light giving the signal 'we think something is wrong' go check with a professional. Since its some of these vitals are not 24h you can also send the 'log' of the event (like in a car) for example the ECG that the watch made while not perfect and we hope a full 10lead ECG can confirm its better than nothing.
That's not at all how watches work. For example, the Garmin watches don't have exposed metallic frames. They're using green LEDs to watch for pulsation in the venous system. It's wildly different tech than ecg Which disproves the entire premise of this video, that they're 2 leed vs 12 leeds ecg.... Consult a biomed tech specialist before talking about technology. They're the guys in the basement of your hospital that fix medical equipment, you know the ones paid way more than doctors for a 4yr degree
I am a 66 year old who got an Apple Watch in 2020. It picked up and kept alerting me to a low heart rate. I used the ecg function to record my heart rate and showed this to my doctor. She put me on a 12 lead ecg and sent me to a cardiologist after that. In August of 2021 I received a pacemaker to control Sick Sinus Syndrome. Without the feedback from the watch I might have ignored the symptoms, passed out while driving and killed myself or someone else. There is a place for wearable technology especially when it prompts you to go to your doctor. My pacemaker will do a much better job of reporting any rhythm irregularities but I have to thank the Apple Watch for the initial detection of the issues I was having.
Thats your job.. It might save a few Stacey's. Filtering and trying to get the false detections down is important but its way better than not detecting at all just because its too much work. Get better tools and methods on your side.
Smart watches aren't accurate but neither is medical equipment. That's why they tell you to average blood pressure readings and heart rates can show 140 one second and 40 the next.
You're right, averages and trends with any med-tech are always more useful than snapshot readings, since we're always adapting to our environment . If we kept a pulse of 60 bpm every second, we'd collapse every time we needed to run somewhere!
Interesting and actionable but the music was very distracting.

How about the latest models? Fitbit has fb sense 2, theres also apple watch 8 and galaxy watch 5 now. I do have irregular heart rhythm and I do want something that's accurate. Which one do you recommend?
I couldn't find any published research that specifically mentions these devices. Its a big issue in the industry - knowing yesterday's model and algorithm are accurate is one thing, but what about newer versions? It's why the comparison study I reference is pretty big news in this space (albeit using older models).
If you put a gun to my head though, I'd probably lean towards the Apple Watch 8. That's because looking at older models, Apple seem to have developed an accurate algorithm for detection of irregular heart rhythms that is always amongst the best. In addition to this, there are more journal publications on the use of Apple Watches for a variety of medical use cases that for the others. This doesn't neccessarily mean its better - but it means that if we discover more uses for this kind of technology, its more likely we'll find them for the Apple Watch before the others, if this trend continues.
@Mickle Doc Hey thanks so much for the reply! Really appreciate it. Awesome video too btw!
Thanks for sharing your recommendation. I started following development updates for wearables with ecg 2 years ago when I found out I had some form of tachycardia... honestly was hoping to hear more praises towards the cheaper models as I'm not an iphone user (plus apple watch is more expensive than the rest) and the watch is unusable without an iphone. But yeah, at the back of my head, I do think joining the dark side might be a better investment health-wise. And I've been postponing this decision for way too long. Anyway, thanks so much for your insights!
P.s. My cardiologist specifically recommended only the apple watch (q2 2021 so maybe series 5/6) and I kinda thought he was just an apple fanboy
@@crazybits9257 This is also the reason I'm considering an apple watch 8, even though I don't even have an iPhone. There is another youtube channel called the quantified scientist who uses real world data to compare health trackers (ruclips.net/video/YVhmzxpw5Gg/видео.html) and he also found that Apple watches are the most accurate.
Hi I am a Android User Which Watch is best among these two for heart Tracking and ECG, Galaxy Watch 4 or Fitbit Charge 5 ?
Fitbit Charge 5 is now owner by Google and will require Google account. May not matter to you where your data is stored but users who dont want to give Google their fitness data will lose al their data. Just thought I'd share.
So Fitbit have reduced the False Positive rate but we don't know the False Negative rate? Doesn't sound like an investment to me ...!
You would rather have a false positive and test using the ECG function and when still in doubt goto the hospital to get a ecg than not detecting at all. Also not sure why he uses such old models even when making this video apple for example had already supported this for 3 years (first watch todo this was model 7 released a full 2 years before the video). For me apple watch 7 and new models have never detected a afib when it was not happening also in background mode. Detecting as a 'signal' so we can test is always 100% better than not knowing at all. Its like saying lets not put seatbelts on because some people still get killed.
Thank you for the vid. I am still not sure if a watch is right for me. Can you do a vid about the Kardia mobile? Please allow me to share an other comment, not to be rude or anything, but please consider lowering the volume of the background music in future vids (or not using it at all), greetings
Great suggestion @kingraw2000! I'll line up Kardia Mobile for a future review. And apologies about the background music - I've had similar feedback from a few viewers, so hopefully you'll see (or hear!) and improvement in future vids. Thanks for your support!
Your chart says that Kardia mobile is less accurate than Apple Watch 6. Have both. The Kardia takes a three point reading and shows six leads in the graph. My cardiologist says the Kardia gives more information, but neither the Kardia nor the watch are really useful in his opinion with the Kardia being somewhat more useful than the watch. He would prefer that I wear a device continuously, which is embedded under my skin. That doesn’t sound comfortable.
Have a look at the Fourth Frontier chest ECG. It is good enough for Paula Radcliffe and gives you continuous ECG.
I will do, thanks for the tip. I used to use a MyZone chest strap for heart rate monitoring too - it was consistently more accurate than my wrist-based wearables, so I tended to use it alongside my Smart Watch when exercising. Makes sense that the same principle would apply for ECG monitoring
@@MickleDoc I've been using it for heart issues and it's a lifesaver and the people running it are also very helpful. The device will record a single source ECG (lead 5?) for up to 24 hours, it is synced to the cloud and the link can then be sent directly to the cardiologist. Real-time ECG's can also be monitored. The cost might seem high but it is less than the private cost of a 3 day Holter monitor.
It is being sold as a fitness device but it's real benefit is for people like myself.
If one finds out he has intermittent fibrillation, can anything be done about it currently?
Unfortunately no!
So, why one needs to find this out?
In the UK, there is plenty we might still offer someone with intermittent AFib depending on their other risk factors. I would recommend that anyone who thinks they may have intermittent AFib speak with their medical team.
@@MickleDoc would you please name a few of these possible interventions?
@@ml3141 I'm going through this right now. Options are: 1). Do nothing as Afib is not necessarily dangerous in and of itself but could be if you have other factors. 2). If you have a sustained Afib episode you can have it cardioverted to sinus rhythm either electrically or with a drug -- under medical supervision usually at an ER. This ends the episode but many times it returns (but not always). 3). You can take a rate control medication like a beta blocker if you Afib is the type with a high heart rate. And also take an anti-arrhythmic drug like digoxin or flecainide to reduce the arrythmia. These would be all the time. Drugs have side effects. 4). You could practice "pill in the pocket" strategy which is to take the prescribed rate control and anti-arrhythmic drugs as needed however this is a decision that mut be made in close consult with the medical team base don your risk factors and other drugs. 5). You can get an ablation that is an invasive but usually safe surgery where the doctor freezes or cuts the nerve on your heart that is sending the bothersome signals. Sometimes it works, sometimes it needs subsequent procedures. Of course risk is always present in procedures. 6). There is a new device called a Watchman that prevents clots that are the most dangerous possible effect of Afib. I am not a doctor but a new Afib patient and am considering options so just sharing.
I wanted to watch the video but the music doesn't sit right with me, I hear it more than I hear you. It's bothersome. I only lasted a minute. I'm out.
Excelent video. Thanks!
Nice video! Thank you, directly from Brazil.
My watch picked up an arrhythmia that was not picked up on 12 lead ekg at drs… I’m a believer…
You have a better chance of catching it with multiple smart watch readings than a single ecg from the doctor.
You usually wear a 24 hour Holter monitor to catch it, since most arrhythmias aren't constant.
Which watch do you have?
@@bobozwald3234 Or daily both tools have its value but they better tool can only detect it when its attached the power of watch versions you can have them on 23.5+ hours a day all year.
Just found your channel and subscribed. Been having lots of problems getting my health professionals to take my b12 deficiency seriously. Despite producing multiple evidence that it improves my long covid symptoms I can’t get them to increase them to more than monthly. The ignorance of the NICE guidelines and the benefits of b12 injections for particular Patients is frightening.
B12? Why do you need a doc to prescribe that instead of just bypassing them and supplementing with over the counter oral b12?
@@dmora2386 Because you need injections. Supplements don’t work if you have absorption problems
In many cases, after about a year the watch can't read the ECG any more. Don't buy it if the ECG functions. That happened to my watch, funny just after the warranty expired.
In April 2022 I had a lacuna infarction and my apple watch did not tell me
Does it detect VTACH?
Back In August of this year I had a stoke due to a AFIB. I am 47 years old. I weight 205 pounds 6 ft. I am in good health or thought I was. I picked up a samsung watch to monitor myself. This was after I had to ware a monitor for 2 weeks after leaving the hospital. I am not sure if this works accurately or not but I now have a eye out on my heart rhythm now.
It is scary and I did sneak up in me. I suggest everyone should just be aware of this. 4 months later and I am back to 80% on my right side. I do experience brain fog from time to time.
Everyone should get a smart device it could save them.
Good information, but the background music is annoyingly too loud. Thanks.
Frankly, it nearly ruins the video.
The stethoscope around your neck verifies you’re a physician? Take that thing off unless you’re in clinic.
How accurate are the doctor's electronic device's? Are they certified daily?
That was great, Tom. Like many runners I wear a Garmin forerunner watch that has a heart rate monitor. That feeds into zones in Strava. My issue with that is it assumes a standard calculation to work out the maximum heart rate - 220 minus age. Based on that I should be dead, so as a keen athlete how can I work out what the correct heart rate zones should be?
Unfortunatley, there's no great solution to this. Several different formulas have been developed (the one you refer to is the Fox Formula, but there are others, like the Tanaka formula) but they all fall foul of over or under estimates. You might be best using a heart monitor (chest straps more accurate that wrist watches) and matching HR with your self-perceived exercise intensity, in order to map out your own, personalised heart rate zones.
@@MickleDoc Thanks Tom, that's what I've been doing so it's nice to know I'm doing something like the right thing :)
Just wondering why did you use old models?
Good question. It's because independent research comparing wearables is rare! This was the best research paper I could find on the subject with multiple participants (rather than just one person's review). Hopefully it still gives an idea of how the different algorithms can vary and that for some companies, the reality doesn't always match the marketing!
Hello! Dc Tom, the video is helpful but I just have a little question, would be able to tell me how accurate(ECG) is on apple smart watch series 8 which there are the latest versions with the latest versions of software
Thanks
Hi, great question. I've just had a look though and I'm afraid I can't find any publicly-available research specifically on the series 8. Apple doesn't tend to post research on their website and I can't see any published papers on the online research database I use. I'll keep a look out though!

Sorry for such a dumb question will this pick up ST elevation?
Doc you have ST elevation on the 2nd from bottom chart
Great video
If a patient had a history of ECG irregularities, it could be possible to install micro transmitters, on or in the thoracic cavity, to give true multi-channel ECG.
The background "sounds" (not really music) seriously distract from your important message.
Great video, BUT please REMOVE THE BACKGROUND NOISE. ACTUALLY, REMOVE THE FRONT NOISE!!
Apple Watch Heart Rate Sensor is very accurate up to 98% - 99%, The Apple Watch tracks heart rate using photoplethysmography
background music way too loud, can't hear clearly
very insightful. thanks for sharing this.👍
Glad you enjoyed it Rohan, thanks for the feedback!
Apple Watch woke me up with a Notification of Afib. This indicated constant monitoring. Not correctly reported.
Yes he used a very old model (6) by the time the video was released we already had this background mode for about 2 years. While a useful video its a pity he talks about progress in the field but also used such a old model even a year ago.
Why use such old data? talking about the apple watch 6. The apple watch 7 and 8 where already released and also detected afib for example. My apple watch 7 picked up my afib during the day and started giving warnings >2.5 years ago. So it also supported the '24h detect mode'. I am not saying this video is not interesting but time has moved on we are close to the release of apple watch 10 already. Also while its true we have not seen how much/often it misses afib we do know its way way way more than not having any way to detect them 24h/day or even using the ECG if you feel weird. I always send my ecg to the hospital and they can work with this if anything new is happening they will call me in for the 'many wires one' to confirm a change. Its a great 'easy to have on' tool to keep track of things even if its not proof of anything at 100%. Its conclusion should be is it a 'confident hint' that can be used to talk to someone or go in for a test is a clear yes and thats is so much more than we had before.
There is a new watch called Cardiac Sense and it’s Israel technology and supposed to be very very accurate. But it’s expensive. Do you have any idea about this as I have MVP and AFib and I am told by my cardiologist to wear one?
FITVII WATCH GT5 APPROVED BY FDA
Long boring explanation.. be sharp to the point, the music definitely adds to more irritation
fun fact: unless you use a samsung phone, the ECG on the galaxy watch 7 is disabled. Smasung would rather you die than not have all of your money.
Lose the music
well that explains why mum was flatlining when I tried it, I was holding the crown for her.
You can have fun with the detection using 2 or more people and making sure the 'loop' is complete you can 'test' 2 or 3 people at the same time :)
I just did two readings
Standing up 237
Lying down 094
?
The music is distracting and unnecessary
Sounds like a lot anxiety when you start using it
10 leads on the chest? Are you sure about that?
Sorry Doc, but we don't need an ECG on the wrist. First, no one other than a trained professional can read and interpret such a chart.
What we - really - need is a big red Engine Check light on the wrist.
A trained profession can only look at it if he well looks. Software might not be 100% correct and as pointed out only has 1 datapoint but its better than not having ANY hints at all. Its like not having any engine lights and just waiting for the car to stop and yell 'clearly something is wrong now'. Also second remark is kind of silly a modern watch can now check 4 or 5 vitals making it very much like a engine check light giving the signal 'we think something is wrong' go check with a professional. Since its some of these vitals are not 24h you can also send the 'log' of the event (like in a car) for example the ECG that the watch made while not perfect and we hope a full 10lead ECG can confirm its better than nothing.
That's not at all how watches work. For example, the Garmin watches don't have exposed metallic frames.
They're using green LEDs to watch for pulsation in the venous system. It's wildly different tech than ecg
Which disproves the entire premise of this video, that they're 2 leed vs 12 leeds ecg....
Consult a biomed tech specialist before talking about technology. They're the guys in the basement of your hospital that fix medical equipment, you know the ones paid way more than doctors for a 4yr degree
👍we need more additional health professional help
The loud and noisy background music made this barely watchable, sorry
Thanks for the honest feedback - I think I went wrong with the audio in this vid. Will make sure I turn it down a notch in the next one
I am a 66 year old who got an Apple Watch in 2020. It picked up and kept alerting me to a low heart rate. I used the ecg function to record my heart rate and showed this to my doctor. She put me on a 12 lead ecg and sent me to a cardiologist after that. In August of 2021 I received a pacemaker to control Sick Sinus Syndrome. Without the feedback from the watch I might have ignored the symptoms, passed out while driving and killed myself or someone else. There is a place for wearable technology especially when it prompts you to go to your doctor. My pacemaker will do a much better job of reporting any rhythm irregularities but I have to thank the Apple Watch for the initial detection of the issues I was having.
why do all these youtubers put music in the background this is video is useless since you cant hear any of the info hes talking about.
🎉 Shocking
Video very noisy
The background music is totally unnecessary
The last thing I need as a doctor is 21 year old Stacey sending me a million “abnormal” ecgs after heavy night out every Friday
Haha funny.
Thats your job.. It might save a few Stacey's. Filtering and trying to get the false detections down is important but its way better than not detecting at all just because its too much work. Get better tools and methods on your side.
The music was awful and unnecessary
Smart watches aren't accurate but neither is medical equipment. That's why they tell you to average blood pressure readings and heart rates can show 140 one second and 40 the next.
You're right, averages and trends with any med-tech are always more useful than snapshot readings, since we're always adapting to our environment . If we kept a pulse of 60 bpm every second, we'd collapse every time we needed to run somewhere!
Could be the device is not attached properly...
Dude you give off serial killer vibes.
Cant it tell if you are having an st elevation?
