Thank you 100 times!!! I am in nursing school and I tell you I cannot remember things that I have to read in my book very well because the why and the how behind the murmurs is not important when learning how to do a physical assessment of the heart and neck.
Before I watched this video, I tried to remember and regurgitate everything about S1, S2, APe To Man, definition of murmur, 2nd left intercostal space, blah blah that I could, but my memory is weak using this method, I forget things a little too easily like this.
However, for some reason, if I just watch a video on HOW the heart works and WHY you hear a murmur in this area or WHY it radiates to the axilla, I remember it 10 times better!!
So thank you so much for these videos. They really help.
I agree with another commentator that said it would be more beneficial to hear each heart sound after the explanation to help solidify what we just learned. otherwise great video!
Which idiots didn't like this video? Amazing!! thank you for your efforts. It helps me so much
0:12 Aortic stenosis
0:19 Mitral Regurg
0:25 Mitral valve prolapse
0:35 Aortic regurg
0:43 Mitral Stenosis
0:53 S3
0:57 S4
Thanks! I think, it should be in the video :D
Really helpful, thanks
Not all heroes wear capes! Thank you!
Noice
Thank you!
The heart is such an amazingly elegant system. Well done evolution.
Super good video for EMT's and anyone. Thank you!!!!
you are the best teacher in the world
Thank you! It's very clear to understand this topic...
Very neatly put. Interesting, informative and simple.
The best video in cardio!Thank you
this is great thank you
Never imagined this was understandable. Wow! Thank you!
Awesome Explanation.. best i ever heard thanq so much...
Excellent presentation. Love it ❤
Excellent video.Thanks.
Thanks a lot for such helping video.
Fantastic production; great for cementing all these concepts.
Great video!! Thank you so much!
Excellent presentation
Vry hlpful.. thnks doctor
Nothing to say just ... Thanks 😍
Pefect presentation.
GREAT !
Thank you very much. This really helped me a lot!
Fantastic, thank you!
THANK YOU SO MUCH!!
You just got me an 91 out of 100!!( Portuguese table thingy thing)
Too good doc.
mine is innocent but I just need to keep doing vigorous exercises which I have yet to do. The hole in my heart is the size of the tip of a pen, so it squirts blood outside of my heart, but not an alarming amount. The blood eventually goes away before it reaches my lungs. But it can be dangerous if the hole is bigger because the blood can form a muscle around the heart and squeeze it. That won't kill you on the spot because u will notice that u are having breathing problems and the outcome depends on how much you want to live, assuming you want to live you will tell a doctor *immediately*
HELP PLEASE: At the end of systole, RV pressure< Pulmonary artery pressure & LV pressure< Aortic pressure Is that correct? Because I cannot find any values documented for end-systolic ventricular pressures.
Thanks a lot!!!
Simply excellent. Very grateful for clear, concise and well presented video. Thank you for the great channel. 8/8/2018 😊
omg thank you soooooooo much!!!!
great
awesome
BEST BEST BEST THANKZ
Sounds like a rapid or faster heart beat. Athletes like myself seems like our hearts beat slower. Is this common?
yes athletes have higher stroke volumes, so their hearts don't need to beat so fast because the heart is more efficient
Interesting.
Perfect video!
heart mur mur nice video share anyway
THIS VIDEO IS QUITE USEFUL. THANK YOU
i dont understand but i am interested . a 13 year old kiddo here watching med haha
I have a heart murmur
Excellent presentation. To make it even better, they should replay the murmur sounds after they explain the cause of each murmur. The only time they play the sounds is before they explain the cause. Otherwise, it's great!
+Simple Hermit 😂lol
Jordan b
+Simple Hermit Name checks out. XD
what is the name of the program he used?
This sounds apply for dogs/cats?
excellent video, but as a Physician of over 12 years, I can tell you that hearing the nuances, like crescendo/decrescendo and ejection clicks, etc. is EXTREMELY difficult unless you are really gifted at this skill. You are lucky to get a location, radiation and whether it's systolic or diastolic; nearly every physician will need an echocardiogram to nail down the exact murmur type at that point. On paper though, it's importnat to know about the other features for boards questions and the like.
My daughter is 19 months and just now I am being told she has a murmur
+Melissa Melissa OK. What is the timing of the murmur (systolic or diastolic), the volume of it (1,2,3,4,5 or 6), and the location (aortic, pulmonic, tricuspid, or mitral)? MANY MANY children have soft systolic murmurs that are not signs of any heart problems, We call them "innocent murmurs". When you find out the exact condition that causes the murmur, please let me know what it is called. Thanks
jawojnicki h
I agree entirely with that
I know this comment is old and this is probably a dumb question but. Why are they so hard to hear? is there a specific reason or is it just how it is?
This is the best video on heart murmurs ever , thank you very much sir ! You are a Genius
thanks from Japan.
Before watching this, I have never imagined that I could understand this topic.
河村翔平 same haha
Im not even a physicist. I dont know why im watching this☠️
You explained in 12min what multiple professors failed to explain in an entire semester 🥺 Thank u!
How do ik my dog has a murmur then
Funnily enough, every time I am admitted to the hospital for anything that isn't an emergency my faint Aortic murmur is used as a case study example for medical students/interns at the hospital! It's nice to know what's actually happening there!
I like mitral regurgitation for some reason. I don't know why.
Because you don't have it, I'm guessing!! ;O) :OP
Definitely because you don't have it. It is absolutely horrible. Can't breathe, sleep or do any activities you love doing. Walking 15 feet winds me and then the heart muscle begins to hurt terribly...
This has cleared up so much confusion from my cardiology placement. I finally know what "pan-systolic" means :)
it would be great if you labelled the murmurs in the beginning of the video, or played them again when\after describing them.
I wanted to see this because I have a heart murmur so thank you!
tori johnsen does it affect you? Can it kill you? Im really scared about this. It sounds very serious, is it?
I also have it
I have one too, I'm going to a cardiologist next week
Most simple explanation for murmurs I have found so far. Brilliant that you explain what is happening in the heart as you go along using a diagram. Very helpful, thank you.
This is FANTASTIC!!! Thanks for posting. I found them right on time. THANK YOU SOOOOOO MUCH!!! I have 2 weeks to learn these!

Mine sounds like none of these ahhhhhh it's like buh ba-dum but then changes to bu-ba ba-dum. I thought it was s2 or something.
My cat has a murmur and I am really worried
SonsyGaming YT are you okay? Does it affect you? Can it kill you? It sounds serious..is it?
Now I'm stuck here with my stethoscope listening to my heart just in case I have a murmur
I have listened to hearts, but only for the pulse (regular or irregular) For the murmur I was hoping they would have started with the sound of a normal heart then that of the murmurs. That plus replay sound after each presentation. Even with that, this was super helpful> great explanation:)
I have a heart murmer and it turned out one of our cats had one and wr never knew even the vets didnt know i was like wow hes just like me..had a very sepcial bond with him...that could of been why..he knew my heart was different like his..i had him since i was a baby..sadly he passed as age 23 same age as me...am 26 now and i still miss him... he was always there
great video...but american pronunciation of this always makes me giggle. one example systole (sis-toe-lee rather than sis-toe-l). how do you pronounce stole (ie he stole my hat)? because to me the word is just sy-stole. 😂 oh the us vs uk dialogue debate continues.
hanzib31 I've never heard it pronounced with an "ee" at the end... Ever! Interesting!
I've always pronounced (sis tol). This is the 2nd video I've watched this evening with the wrong pronunciation used. Not a US vs UK issue, I don't think. It is annoying.
It's Sys-to-lee, Di-as-to-lee for sure.
i have been taught to pronunced like that and we can see the proofs all over Google.
where do you get those "sys-tole" pronunciation from? Make it up from your common sense?
do you even study in this field?
Jirapat Thn yes I do study in this field. ive had a lot of teachers, lecturers and professors and I've never heard one of them pronounce it sis-to-lee...always si-stole. none of my peers pronounce it the way you said either.
hanzib31 same applies back here at home
I just found out I have a murmur went to the doctor today
Hii how was that. My docter said me as well the same
my heart makes a noise every tree hours or more is that normal
I'm a medical student and I can't thank enough for providing this.
This is a very helpful video. Easy to understand. The diagrams are good and help me to understand the whole subject better. Thanks for taking your time in producing such good video😉
What software do you use to make the presentation
Hello is anyone out here like me watching these videos for the MCAT prep???????
Lizzie me too
I graduated last month but still sometimes ı watch this video. This is incredibly helpfull to understand cardio.thank you so much for this video..
I own a stethoscope and I try to listen to my heart every once in awhile, since I'm prone to chest pain and that stuff.I noticed there are only several instances I can hear my murmur; after any exertion (walking up the stairs), lying or sitting in different positions, and also, how much I exhale (to produce more clear sounds of the heart)
I was told that my murmur is more like swish dub instead of lub dub which I don’t know which one I have
Army medical me 3bar unfit hua hu cardiac murmur me koi trick batao sir please......
is it normal i can't hear s3 even on full volume? 😢 i wanna hear i wanna believe
for your kind information......word crescendo and decrescendo both are Spanish words,, mean increasing(crescendo),and decreasing(decrescendo).......thnxs
Hello , many thanx I have learned a lot from you but please can you tell me which program are you using ?? anyone can answer please?
Excellent work. Congratulations and thank you 👍
Some EXPERT please confirm this:
1. Closure of M,T=due to intraventricular pressures>intraatrial pressures.
2. Closure of A,P=due to intraventricular pressuresintraventricular pressures.
4. Opening of A,P=due to intraventricular pressures>pressures within Aorta & Pulmonary artery.
Are ALL 4 correct?
I mean all the valves close and open ONLY due to the pressure difference? Or there is some other mechanism behind it like:
1. Ventricular relaxation --> tightening of chordae tendineae --> opening of M,T valves.
2. Does the pressure within ventricles drop enough that it goes lower than the pressure within Aorta and Pulmonary artery? I couldn't find any notation of the values for these pressures.
THANK YOU!
I don't think that's listening on auscultation equipment. I don't hear it through the stethoscope but we're not supposed to use the bell side and this one doctor, that's ALL he'll use. I don't understand why, I don't believe I'm allowed to ask. I'm a paramedic, he's a doctor. My self-imposed rule is don't ask too many questions. Some doctors hate questions.
I've heard all the sounds, I just haven't heard the background sound that resembles white noise, as if it were done on an echocardiogram.
I know someone who has Mitral Valve prolapse. I think my dad has it now. What he described as putting him in the hospital for 8 days sounded like a complication of mitral valve prolapse.
As per Ayurvedic point of view, abnormal heart rhythm comes under "Hridroga". Imbalance of dosha (Vata, Pitta & Kapha) is the reason for any disease. if you face Cardiac Arrhythmia Then take (Heart Care Pack) #planetayurveda for Ayurvedic treatment of abnormal heart rhythms (arrhythmia).
Would you consider doing a series tailored to veterinary cardiology? This was extremely helpful as far as physiology goes but obviously the anatomy is a bit different
Excellent tutorial! Thank you.
Thank you i never seen doctor like you i love to be v may doctor thanks again
My kids are better be smart otherwise we both have to sit and watch these videos all over again
Wow this video is brilliant.... So much simplified...... Perfect like logic and reasoning

i have an Innocent heart murmur witch means it's not serious and it will go away when I'm 15 16 17 18 19 or 20
My heart sounds pretty weird,it's like you drum 2 fingers consecutively,and then drum another finger (3rd finger) after a pause from the 2 previous consecutive drumming.It also beats slower than all the sounds heard from this video which is y I'm looking up for healthy heart sounds 😂
Okay this is driving me crazy and I don't know if there's already an answer to this but my book for nursing school says S1 murmurs are heard louder at the Apex but this video is telling me that the aortic stenosis murmur which is in S1 murmur is heard louder at the aortic point which is not bapex more the base so can you give me the reason why my book would tell me this versus what you're telling me?
i’ve been told I have a heart murmur but never which kind. tonight i’ve been having severe chest pain so i’m deciding to go to the ER or not. I listened to my heart from all angles with a stethoscope and it sounds like a loud rubbing/dragging sound. the example it matches best seems to be aortic regurgitation or possibly aortic stenosis. I also noticed there a frequent triple beats too.
My brother just had aortic valve replacement, due to stenosis, on May 9...... His valve was also leaking blood.....back into the ventricle, as I am understanding this more.....
I am already fascinated with all of this kind of teaching, even WITHOUT my brother having surgery, ever since I was growing up, and so thank you for all of these videos.... Wish we had the internet when I was in school....
i am a dumbass for not clicking on this video years ago
Am I the only one that kinda feels like your heart mimicks the rhythms and extra heart sounds but goes back to normal afterwards?!
What are the blue structures at 3:39 supposed to represent? What are the white rays emanating from the blue? This needs clarification, can some one explain?
Man you are awesome i love you !!! :)
I have an irregular heartbeat called B9 heartbeat.. I don't really know why mine sounds like.
love this guy but doesn't he have his rights and lefts mixed up? I view his diagram in the supine position. what we view as left is actually right.
Great video! Im no medical professional I just have a passionate curiosity and this video was so interesting and thorough. Thanks for your time and for sharing this. Subbed.
Looking for audio of healthy patients’ hearts through a stethoscope, compared to audio of auscultations of hearts with issues or in or in poor health.
Cheers!!! 😊
How does Khanacademy know everything about everything???
thank you this is the best ever I watch ^^
Thank you sir for helping and inspiring me...
Taking inspiration from you I also made some for helping undergraduate medical student worldwide from reference book .
Thank you all Khan academy team for inspiring ..keep helping sir...
I didn't get or see any diastolic murmurs.
very educational thanks for the link mr cat
