ECGs - How they work 

This is the best video for ecg on RU-vid. Period.

Thank you for being a better teacher than our so called "highly trained" professors.

Your channel is the best medicine content channel on RU-vid. Truly appreciate all the effort that goes behind every video and building the 3D models on your website!! You are honestly a great teacher Ruben!! So blessed to have you :)

Wonderful, wonderful, wonderful channel! I'm so glad to have found you, Dr!

That was amazing! You do a great job of making complicated topics easy to understand. The 3D models have changed the game!

ok this is one of the best videos about this theme i have ever seen, i m an italian med student and this was really helpful thank you so much.

Ive watched the whole youtube and all my lectures and this is by faaar the best and most intuitive explanation of ECG ive seen. Great job!

Amazing 3D representation that made the content very simple to understand, never seen anyone explain this topic so effectively , well done.

Great work man...! You win our hearts with this one. Really appreciate your effort. Again great work. Please keep doing this nobel work.

As always, incredibly informative, educational and clear! Thank you

Perfectly simple, great job

This is realy nice explanation . The most of the educators don't tell how it's works .

Thank you for this video! I’m just starting a cardiac physiology course. This was so insightful. Thank you!!

Man, you don't know what I would give for you to be the teacher in my med school. Good video

This was beautifully explained and illustrated

Wow what simplification. Great job!

Thank you so much! You explained it so simply and the animation was great and very helpful. Thank you so much. Now I can read in my textbook and it actually makes sense.

Wow! This was incredibly well explained, simple enough but thorough nonetheless. Thank you endlessly from a vet student! :)

Dude the 3 view animation of the the precordial leads was awesome. It makes so much sense now.

eagerly awaiting the follow-up video... great job :-)

Absolutely beautiful

Thank u so much dr. Waiting eagerly for the next video.

This video saved my life thank u

Amazing, precise information thx a lot waiting for secound video

It's amazing that how much easy one cam represent ECG like you. You are doing a great job reuben! I have sent you an e-mail. If you're free,please do try to respond. Loving your work!

this is the best video ever

great job

Exellent😊

Thank you so much

great video

i love your videos so much !! can you please make a video explaining arteries of the pelvis ....

amazing video best explanation till now but I can't understand how an electrode in the arm can detect the electrical flow in the heart, how does the mechanism of that work?

Awesome.

Kindly consider making a 3d modle of the nasal cavity, especially the lateral wall, containing the middle meatus, infundibulum, hiatus semilunaris, bulla ethmoidalis, lamina papyracea, and osteomeatal complex . I have never understood all of these

Incredible video! I wouldn't have been able to understand the ECG without it. I was wondering if you could explain the pterygopalatine fossa in the future?

thanks alot for that amazing illustration. Could you tell me which textbook mention ECG in that brilliant way,please? Thanks alot.

Thank you so much, one question, in 5:08 you said that the right bundle of His depolarizes before the left bundle, isn’t the left one depolarizes first ?

When will you upload part2

Can you please explain how electricity flows from the skin to electrodes (ECG) to make electrons move in the wire? Is it the electric field or some electrons jump from the skin surface move into the wire?

This is how you explain in detail, loved the way you explained why there is a negative drop for Q and S wave. Like and subscribe from me 👍

What is inside the silver probe? Just a kind of flat surface metal, or a kind of coil forming an inductor/magnetic antenna?

Legend

Part 2?

When will next video come

Can you explain why is the repolarisation T wave gives positive deflection on ecg?

make video of Electroretinigraphy, electroculography, Visually evoked potential

I mean, are these machines reading mV signals??! How does the machine pick up such small electrical signals and not pick up noise from say.... power outlets in the doctor office?!

vay be anladım

Why don't you put 3D videos of thorax and abdomen

those bloody "djing cells"

You got the entire sign convention of the current wrong.

Current is wrong, it’s a potential difference, when the potential change crosses the electrical midpoint between both electrodes, the potential difference decreases. The rate of change of potential is the same per the depolarisation speed, the r complex is completely wrong in your description. When it is half polarised, the potential difference it’s at maximum, when it is fully polarised, the potential difference is again 0.
