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.

[@thecerebrum.]

This is the best video for ecg on KZbin. Period.

[@user-uh2cr9so8l]

Yes! I cant find the next video :(

[@jay9204]

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

[@vitoriaferreira6740]

oh gosh, yes!

[@VictorSantos-ze3ek]

I dont understand why their like that

[@neharao9939]

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

[@aishwaryapradeep7966]

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

[@kevina5018]

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.

[@LM-ek6qo]

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

[@martindagnev8821]

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!

[@ZoubiMed]

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

[@middleearth4841]

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

[@postmortem495]

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

[@peachettte]

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

[@harshilk1859]

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

[@CesarAHaro]

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

[@christapenman4240]

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

[@anna-eq4kx]

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.

[@Stealthsilent1337]

Wow what simplification. Great job!

[@pavanbevoor8636]

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

[@ivo3185]

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

[@shoaax5461]

Perfectly simple, great job

[@narmadharajendran]

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

[@ayhamhalalsheh221]

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?

[@ivo3185]

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?

[@aboutmedicine]

Great idea. I’ll get on it as soon as possible 🙏

[@ivo3185]

@@aboutmedicine Thank you so much! Love your channel.

[@savierosj74]

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!

[@lavieestdrole3793]

This video saved my life thank u

[@neharao9939]

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

[@nouranalmerstani9142]

this is the best video ever

[@thespectre2012]

Absolutely beautiful

[@akramqasim8598]

Amazing, precise information thx a lot waiting for secound video

[@texastexas4541]

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?

[@سجاد-ك8د5ذ]

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

[@mananchawda]

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

[@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 ?

[@lonewolfe2502]

No, I think you're right. That's what I red too.

[@nrbgamingYT]

The patient’s right, not right from our perspective. I believe.

[@StrsAmbrg]

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

[@tonydagun]

great job

[@chandrashekaras1856]

When will you upload part2

[@train4905]

Exellent😊

[@hananmohamed9302]

Thank you so much

[@avishkamalinda6359]

great video

[@ericchin739]

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?!

[@buriburi_kun4020]

Why was Silver (Ag) sad? Because, she couldn't get the Plumbum (Pb) role in ECG audition.

[@saimsiddiqui9893]

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 👍

[@Mavihs27]

Part 2?

[@palwashaumar8257]

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

[@bobeighteen]

5:30

[@VincentSh]

(Med. Physiology Prof.) In lead II, the negative pole is at the base and the positive is at the apex. A depolarisation wave from the negative toward the positive pole causes an upward deflection and the opposite is true for a replolarisation wave. Depolarisation of the ventricles starts from the endocardium and proceeds to the epicardium. Owing to to shorter durations of action potentials in the epicardial regions compared to endocardial regions, repolarisation starts from the epicardium and proceeds to the endocardium. So, you have a repolarisation wave moving away from the positive pole toward the negative pole, hence the positive deflection.

[@zuperman11]

Awesome.

[@hariomtripathi3345]

When will next video come

[@muhammadqureshi5271]

Legend

[@AbhishekSingh-lu8tw]

make video of Electroretinigraphy, electroculography, Visually evoked potential

[@Ranjankumar-gr8is]

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

[@Soneoak]

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.

[@literallynobody1480]

vay be anladım

[@dilishjoylobo3834]

You got the entire sign convention of the current wrong.

[@petrnovak1964]

those bloody "djing cells"
