WOW, who are you. That has got to be by far the most bestest and fantasticous explanational video I have come across since I started studying. I LOVE LOVE LOVE your format. Thank you for taking the time to draw all those cells and all those lines. If KZbin gave Grammy's, YOU would win. :)

[@MyteeBumbleBee]

Right? Excellent presentation!

[@susang6149]

what would we do without you.... you save tons of time.

[@katwingatebrown9802]

ECG with leads please!!!!

[@MyteeBumbleBee]

OUTSTANDING! The whole thing, Man! SPOT ON! Thank you for a clear and well presented overview! I had to leave my eBook to get a better explanation!

[@1860mc]

The simplest explanation I've seen yet. Thank you so much.

[@anups7542]

you are absolutely incredible. wow my understanding has increased a lot.

[@Dahlic]

Great video!

[@deejones573]

Excellent Explanation, Thanks

[@andyhall3369]

Superb. great for FRCA revision!

[@moni03asu]

yes....u the man!!! great video

[@pleasantpaula]

Wow great lecture. I spent hours wondering how the pacemaker calls and myoctyes worked together. Go the functional syncytium. Thankyou! I am trying to understand Atrial Fibrillations effect on action potential or vice versa. Any tips? Or could I argue that it is not clearly understood as litrature suggests..

[@fofogrey5882]

a loooooot of thanks,,,,,,,,

[@mindfullearner344]

Thank you.

[@youmeh19]

Thanks. You are great Help!

Thank you, can you will be using this with my students.

[@siwenstokes5930]

Fantastic!

[@Trentfully]

Awesome! thank you!

[@Areekat]

Great ....

[@marlenelyles1495]

I’ve just learned the basics of depolarization this week. We only learned the definition so I wanted to understand the meaning and come across your channel. I must say this helps me understand the process way more

[@trirex2547]

in theory, would it be possible to harness the electrons directly from a node using some sort of positive charge and conductor? just wondering

[@mrghost8739]

Why the repolarization of the heart occurs in reverse?

[@danieltaylor6163]

What is the software that is used to draw in this? Love watching these videos!

[@vishwasnagaraju8260]

Beautifully explained! Danke.

[@AgataStonka]

There is one crucial problem with this lesson. The SA/AV node are very SLOW at conducting the signal (0,05m/s) - the bundle and the tracts are the faster (1m/s) and the kardiomiocytes are also 1m/s. His and Purkinje are 4 m/s. Thanks to that slowness in AV we have a delay between the contraction of the atria and the contraction of the ventricles: the signal is almost "stopped" for a moment. But I really liked the rest of the video, thanks for that!

[@munguia824]

This wasn’t relevant to the lesson because it wasn’t an actual 3D animation.... people like you always have to find something wrong. There are SEVERAL ADVANCED VIDEOS on KZbin. People like this one because of the simplicity.

[@DREAMAR16]

simplified to the best... thankx. bro

[@brianwilliams5317]

Nice and simplified, thank you!

[@barbarandrihin5477]

Thanks Rishi. You are awesome!!! I gained a lot of knowledge from watching your videos. Thank you and God Bless you.

[@atlanticapacificaofficial]

Out question of someone close to me: after Cardiac arrest 3 times, coming back, get pace maker - why would later one one get inflammation of aorta. Electrical issue related after issue. This all occurred after getting covid.

[@tomkrys3331]

Genuinely wrote depolarization waze in an a level mock once

[@nikolamarkovic4845]

just tnx

[@bhellar123]

mayocardial cell have t tubule. why they are not mentioned ???? heart cell are striated like skeletal muscle.diffence is platue influx of calcium

[@jouhainahallmans6142]

It has been 7 years since you asked this question 🥺 you are probebly a doctor right now…

[@SiriusFuenmayor]

Great explanation!

[@christinabeahan8596]

Thank you!!!

[@Chessboard24]

great Sir.thanx

[@mastermindj2]

thank you sir

[@kasandraalfonso4499]

This was really difficult to learn without having a step-by-step visual. Thank you so much!

[@marissafernandez9973]

Thank you! I just couldn’t imagine it and I tried so hard, now what I read makes sense ❤️
