This video is good for understanding leads (views) Remember, leads are NOT electrodes. A lead is a certain perspective or view of the heart function. An electrode is the physical tool📷 used to provide the view. That’s why 10 ELECTRODES can provide 12 LEADS🤯
Thank you so much for sharing. I have such a hard time understanding it through lectures, bc I’m more of a visual/hands on learner with repetition. I don’t have to watch the video again bc I understood it the first time....
Hello. thanks for the video. Some of the questions, are: - Is negative electrode always the zero reference for ECG measurement. I didn't find any explanation regarding this in textbook/essay. Please help me to find if anyone has read it - Some books noted that the negative electrode is located at central terminal (which located in the center of the heart). But in this video, for example, the negative electrode located between 2 electrode (i.e., augmented lead) I just need the supported references for my better understanding. Thanks
So the Right leg electrode is an earth electrode. So where's the AVE lead on the 12 lead tracing? Will see Squiggles on the AVE lead if there's an earthquake?
why didn't you continue to explain, I was finally understanding everything and you stopped where I have problems, how the final diagram works, and how to read it!??
Right arm is negative always,it is actually the axis of lead u have to understand.for example lead 2 has negative at right arm and positive left leg.axis of cardiac depolarization is 59 with positively charges moving towards left leg..Hower axis of avR is vertically down ,i;e, right angles to lead 1.so its negative isn't right limb, but the point where mean of the right limb and left limb is zero.it is not necessary it should be negative.as you know charge with +2 units negative with respect to charge of + 10.as charges will flow from higher charge concentration to lower charge concentration till equilibrium is established.Further in heart there is propagation of depolarization. To understand it fully u should understand vectocardiogram.U r welcome to ask where u need,so that I can get rid of any possible confusion
yes logically you feel that you should place the lead on the shoulders and at the lower limb junction but guess what if you put it on the shoulders or the wrist the result will be the same because the electricity will be the same
In physics the flow of electrons is toward the positive electrode. Here, however, it's by convention - the negative electrode serves as zero reference for the positive.
Limb is different from electrode, you are referring to an electrode Leads are those on the ECG script such as AVF, AVL, AVR which are unipolar and I, II, III which are bipolar, add this together is equal to 6, Then for the chest lead(precordial leads) the leads are V1, V2, V3, v4, v5 and V6 That's all that's how it amounts to 12 leads 6limb leads and 6 chest lead

@@bling1349 that one concept slowed my understanding at first!
@@tracyflood1194 Ikr
Small but super important thing to keep in mind!
Amazing point de🌷
Thank u
perfect video for anyone who needs a quick refresher! probably not the best video to learn this for the first time
I was hopelessly lost until this video. Thank you so much!
Why did I read the textbook for 3 hours and still not understanding much while this video explains everything perfectly in 3 minutes
me tooo
work smart, not hard
@@jelleleeuwis4353 lol 😂
Thank you for explaining this as easily and clearly as possible! I finally get it!
sis just explained an entire chapter in 3 minutes damn
All of your videos explain complicated things so clearly they start to seem easy, thank you so much for your work!
Thank you for your comment.
Wow! This really helped me. My professor is expecting us to know this, and I thought it was super difficult till I looked at this video
A very details explanation within very short time.Thanks a lot.
best video ive seen to study how to place the leads
Big thumbs up for the team of alila media
I still don't get it
lmao same here
Same here one of the most complicated shit ever 😂
ist just the most complicated part
Same
Totally!
Thank you so much for sharing. I have such a hard time understanding it through lectures, bc I’m more of a visual/hands on learner with repetition. I don’t have to watch the video again bc I understood it the first time....
It doesn't explain the topic entirely, there's no physics standpoint explanation nor how to read the diagram smh.
This helped me a lot ❤
Didn’t even understand this from DR NAJEEB. U r ECG saviour!!!❤
Its amazing how this machine can capture so much.
Awesome! Effectively, and precisely explained
That was amazing! I finally understand it now!
Thank you so much, I finally understand the leads!
wow, great work compiling this educational animation
Easy to understand, well put. Learned more in this 10 min video then I did in two whole classes! Ty!
Good info in such a brief video!
Thanks for such lovely explanation
It is entirely my fault, but I was lost at 00:30
thank you for this short but very useful video
Thanks its mutch better now
Really thankyou so much.... Very helpful ✨
very precise & helpful
You got my heart❤️❤️❤️
This really helped , thank you
Excellent video class
thanks your video is helpful for me
Thank you so much ❤️❤️❤️
Actually excellent vedio , give more information from little time, thanks i hope continuoe
You guys are simply awsum .....keep rocking ....⚓️💝
awesome*
Thank youuu so much 👏❤
You're welcome 😊
Very helpful , thank you so much
Very informative
Good video!
Excellent video .thanks but I need pdf for words in video 🇸🇾
Thank you ❤❤🤗
Really awesome.....
So helpful. Thanks.
Thank you!
Thank you so much for savin ma life
Thank you very helpful.
Very thanks ♥️♥️♥️♥️♥️♥️♥️♥️♥️
Thank you🌸
Very helpful !
Thank you very much 😊
What do I need to do in order to understand this video fully? Should I review some of school textbooks?
Thanks thanks thanks for it..
Thank you so much
Awesome video tnx
thank you~~ 2:47
Amazing!
very gud 👍
What are the books or references your using?
Thank you
The labeling of lead II and III is somewhat confusing, as the II is on the right, and the III is on the left. 1:45
Hello. thanks for the video. Some of the questions, are:
- Is negative electrode always the zero reference for ECG measurement. I didn't find any explanation regarding this in textbook/essay. Please help me to find if anyone has read it
- Some books noted that the negative electrode is located at central terminal (which located in the center of the heart). But in this video, for example, the negative electrode located between 2 electrode (i.e., augmented lead)
I just need the supported references for my better understanding. Thanks
Did you know the answer.?
10 electrodes to capture 12 signals of interest, referred to here as leads.
Nicely worded. I can remember asking so many people “How can we get a 12 lead EKG when I only have 10 leads (wires) to attach to the patient?”
This helped me so much!!
This is gold
These comments all seem fake..
very wll explained
Where do you get your information, what references?
Why we don't use right leg for attachment of electrode instead of left leg ???
Good one
owsum i got what i wanted to
Wow 🤩
So the Right leg electrode is an earth electrode. So where's the AVE lead on the 12 lead tracing? Will see Squiggles on the AVE lead if there's an earthquake?
Her voice is equivalent to nails on a chalkboard
How about discussing ECG in detail in next video.
Yes it's on our list!
+Alila Medical Media hi
+Alila Medical Media i study about the lead but i dont under stand the uniploer wt is
It's explained in the video, you may want to turn on the "CC" button for subtitles to understand better.
well done :)
Can a right bundle branch block ever be normal? Or is it always serious?
Thanks

why didn't you continue to explain, I was finally understanding everything and you stopped where I have problems, how the final diagram works, and how to read it!??
Those are covered in other videos, you can check them out in our channels.
@@Alilamedicalmedia omg! Thank you so much!!!
How is the same place as right arm can be positive and after that can be negative???? Please answer me

How may hours is the test done?
It takes minutes
So if I get my multimeter and measure voltage(probably some DC mV) between R(Neutral) and L(Live) i'm suppose to get some volatge right? #Just_Curious
how come sometimes the leads on the two shoulders are placed at the wrist? and im still confused on where i should be placing the leads on the legs.
yes logically you feel that you should place the lead on the shoulders and at the lower limb junction but guess what if you put it on the shoulders or the wrist the result will be the same because the electricity will be the same
What is zero ref?
The background level that is considered zero. Similar concept = tare in weighing
Thank you!@@Alilamedicalmedia
What is the difference of the line of sight and the view?
So to understand this videos try to understand the meaning of; Electrode, limb leads and voltage.
Why the view from RA to LL is left view
nice
If you are looking at the heart from a transverse view, does that mean you are looking at the heart from above, i.e. bird's eye view?
love you
Watching this the day before exams cause I forgot the tutorial on this
can anyone tell what's the meaning of depolarization towards the lead?
So....12 lead EKGs are used to assess the function of the _______.
0:25
im a USRN but i dont underatand what this video is trying to tell us
As good as Dubin put it!
How do you decide which electrode is positive/negative, what is substantial physics behind it
In physics the flow of electrons is toward the positive electrode. Here, however, it's by convention - the negative electrode serves as zero reference for the positive.
Am i the only engineering student here, who is watching it for instrumentation`s presentation?
Why is Moira Rose narrating this video
If 1 lead across each limb then 1×4=4
6 across chest then
4+6=10
Then how can be there 6 limb leads
Can anyone explain, I have exams tomorrow 😒
Every single wave mean one
Limb is different from electrode, you are referring to an electrode
Leads are those on the ECG script such as AVF, AVL, AVR which are unipolar and I, II, III which are bipolar, add this together is equal to 6,
Then for the chest lead(precordial leads) the leads are V1, V2, V3, v4, v5 and V6
That's all that's how it amounts to 12 leads
6limb leads and 6 chest lead
