It's been 3 years since I was introduced to ECGs, and I've been since then trying to wrap my head around this very concept.
Only 8 minutes of quality content did what textbooks could not in years.
Superb video, thank you!!!

Honestly I study ECGs every year and then forget everything by the next year... it sucks

[rofiqel]

I guess most of you guys are in med school. I legit don't understand most of what he said but explanation was great for the code I'm writing that represents this for my mechanical engineering class. Good luck future doctors

You know what? We had our first cardiology class in med School (5th year) and I really needed someone to explain me the ECG. This video is perfect and specific. I'm fed up on books spending pages over pages and in the end failing to explain things. Wish our professors used videos as yours in our educational process.

This is the clearest I have ever had ECGs explained to me, through nursing school, and then grad school! I needed to know that electrodes and leads are two different things, though they are related. Now I know what each lead means, and which part of the heart it is recording! Thank you!

I'm shook at how much physics actually goes into ECG's.

I'm dropping out of nursing after this video. Thank you osmosis.

Osmosis, you guys are truly doing god's work. Thank you.

[noorullahhabibi]

listened to my lecturer for 50 minutes in class and another 50 minutes of the lecture recording, but understood nothing; watched this 8.5 minute video and now I know how ECG works.
Thank you so so very much!!!!

You guys did what a 2000 pages books couldn’t do! And only in 8:35 mins.
Nicely done.

[jjlegend]

Absolutely fantastic explanation, cheers!
Only small suggestion would be to mention, that depolarisation & repolarisation of the myocard occur in opposite directions ultimately leading to a positive curve response in both cases on the ECG, which is why the P- & T-waves are usually both depicted as positive.
Failure to mention this might have people confused when trying to interpret an actual ECG.
Nevertheless an excellent video for the basics!

I’m an RN working in a cardiac stress lab trying to gain as much understanding about cardiac electrical currents as possible. Thank you!!!

[bryannadavidson]

I have asked people to explain how ECGs work for 5 years and every time they say what they do but never how they do it, I'm so happy that I know now!

[aishwaryag]

This is the best introduction to ECG EVER

[Pitoleczek]

Generally i know ECG but it took me much time to understand when I was a student. This video is showing clearly basics physiology of heart and i believe it will help students.

[iPadpro]

Just pause the video to write that u did this incredibly, i can now understand those cvs chapters

[sangitah]

Just wow!!! I have no word to write. It was so clearly and magnificently explained. I went to medical College and never understood EKG in depth.. you have beautifully explained EKG...well done..love it !! ❤️ Thank you so much🙏🙏

Not all students can afford the money for a prime subscriber 😞. Although the money could be not that much for a US student, please understand that it's too much to afford for a student coming from a third-world country like me. I understand how the world works and that you need the money but you were doing a really great humanitarian job when you were sharing educational materials with every student in the world. Please reconsider holding the wonderful educational material by osmosis in exchange of money.

Hallo I am from Indonesia I want to riview this video:

EKG secara khusus menunjukkan bagaimana gelombang depolarisasi setiap detakan jantung yang merupakan gelombang mutan positif. Dan tampilanya bergantung pada rangkaian elektroda yang digunakan. Sel elektroda ini disebut lead 2 misalnya dengan satu elektroda di tengah kanan dan dikaki kiri, pada dasarnya saat gelombang bergerak ke arah elektroda kaki kiri akan mendapatkan defleksi positif, seperti defleksi positif besar ini sesuai dengan gelombang yang bergerak ke bawah vertikal kiri dan kanan. Pada saat seseorang beristirahat sel akan bermuatan relatif negatif dibandingkan diluar lingkungan dan ketika mereka mendepolarisasi, sel-sel menjadi bermuatan positif, meninggalkan muatan sedikit negatif diluar lingkungan. Elektroda akan mendeteksi muatan yang ada diluar sel jika muatan yang berada diluar sel cenderung bermuatan positif maka EKG akan menunjukkan tracking tersebut sebagai defleksi positif-semakin besar dipol semakin besar defleksi sehingga akan menunjukkan gambar mengarah ke atas. Sebliknya jika muatan diluar sel cenderung negatif maka akan terjadi depolarisasi dan gambar akan menunjukkan garis lurus.

Thank You

I guess this is the only video on the internet that clearly explains the basics of ecg. Hope to see more of the ecg videos. Great work guys.
