EKG Reading: How the QRS is Made
Vložit
- čas přidán 9. 07. 2024
- (Quick links to topics are below) I explain how the QRS is created, helping the viewer understand rather than memorize when it comes to EKG reading. I review function of the His-Purkinje system, narrow vs wide QRS, bundle branch blocks, ventricular pacing, what is meant by "QRS fusion," and many basic concepts of physiology and anatomy. The video is intended for anyone who looks at and interprets electrocardiograms or telemetry! I hope you enjoy and find the content helpful!

I got here from your comment on a Twitter thread. And now I'm watching this video at 4am. Sleep is for the weak! Absolutely loving your lecture!
One of the best ekg basic tutorial animation
This is by far the best and most comprehensive video explaining EKGs I have ever seen! Thank you, Dr. Cooper!
Ths you for sharing, after watching all the video I do understand deeper about QRS and wide QRS tachycardia in an easy way.
The most comprehensive video explaining ECGS,thank you,keep going
Always
We cannot overstate the importance of truly understanding basic principles ! the phenomenal Dr Cooper
The Best EP channel on CZcams.. No doubt
I have worked with excellent electrophysiologists and EP technicians, who unfortunately did not have the ability to teach. I wish I had seen your lectures in a much earlier stage of my EP career since you have an extraordinary talent for teaching. THANK you very much! Your videos are an inspiration to EP.
Brilliant lecture. Please continue to release these clinical focussed lectures.
Wow , Waiting for these videos nearly 7 months . I wish more electrophysiology videos would also be broadcasted
I think this video is sensational. I’m not in medical field (I wished) but I am hobbyist very interested in arrhythmia and ecg and this video is such a tremendous material and explanation. Thank you doctor.
Thank you, Dr.Cooper ! This is beautifully done. Decided to apply to EP and not IC after watching your videos. Can’t wait for devices timing and different operations.
There is no better compliment than that! Different specialties suit different people, but we can only consider areas we are exposed to during our training, whether that is in-person exposure or remote. It is such an honor to be able to inspire you through this medium!
This is very well explained, thank you! I'm a techie in arrhythmia software and all of your videos have been an excellent resource in catching up on some fundamentals.
This is the best lecture on this topic i ever came across... thanks a ton sir
Thank you, Dr. Cooper. I love how you apply the basic principle and logic to explain various phenomena. I now understand better about BiV timing and how you can assess individual contribution from RV/LV leads and native conduction by looking at EKG. Beautifully done!
Thank you Joshua, missed your videos. EKG was what I was missing most :)
This video is handy for understanding different practical scenarios and their combinations. Thank you, Dr. Cooper!
Congratulations, excellent presentation covering all aspects of ECG tracings, especially CRT and His pacing.
Absolutely fantastic! Once again thank you for taking the time to explain this so well. You are a gifted and wonderful teacher
I did not listen or read before like this very informative lecture, Thank you so much dear professor .
This video is so great! Thank you, Dr.Cooper!
I saw some of your videos! All of them are very useful to me, Dr.Cooper! Do you have any video about SVT and how to differentiate some kinds of them?
Thank you Dr Cooper. Truly excellent electrophysiological and anatomic explanations of different phenomena. The only part that I would have wished to be a bit more in depth is on how to localise the origin of a pvc based on surface EKG. Will definitely explore more of your very educational videos. Thank you again.
PVC localization will be a future topic!! Thanks for the kind note!
Thank you for such wonderful and thorough presentation.
Phenomenal video. It's great learning when someone is doing such an amazing job explaining these concepts. Also the graphics helped a lot. Thank you!
Glad you liked it!
This is very informative. Thank you.
Great presentation. Thank you!
Glad it was helpful!
Great video, I'll definitely be adapting some of this to my own talks!
Thanks so much!! And feel free to make suggestions for improvements or supplements!
Thank you professor Cooper.
SUPER PRESENTATION
Excellent job
....excellent explanation...good job Sir...👍
Un vrai tour de force. Merci.
Invaluable
Thank you.
thank you!!!!
awesome
You promised me a vid on PVC Localization😂
Doctor I also have a question. If you have SVT with aberration, would it mean the normal (after sinus rhythm is restored) ecg should show LBBB or RBBB morphology? Or can you have aberrated SVT without regular ecg showing any block? Thank you 🙏
No, just because SVT has aberrancy doesn't mean sinus rhythm also will. Each bundle branch has a recovery time (aka refractory period), and a heart rate that exceeds a certain critical rate can show aberrancy. This is called a "rate-related bundle branch block" and can result in aberrancy during tachycardia even while sinus has a narrow QRS.
@@dr.joshuacooper-arrhythmia9917 Love the response, thank you.
