ECGs - How they work

A simple explanation of how ECGs, or electrocardiographs, are captured. I've tried to make it easy to understand, but if you have any questions please chuck them in the comments below.

This is part 1 of a forthcoming series - part 2 will explain how to read an ECG.

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

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

[neharao]

Your channel is the best medicine content channel on YouTube. 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 :)

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!

[middleearth]

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

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

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

[peachettte]

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

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

[anna-eqkx]

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.

[محمدتقينبيلظاهرحميدي]

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 ?

[ivo]

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

[pavanbevoor]

Waiting eagerly for the next video.

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?
