EKG Reading: How the QRS is Made

(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 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.

    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.

    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 🙏

  • @dr.joshuacooper-arrhythmia9917

    @dr.joshuacooper-arrhythmia9917

    Жыл бұрын

    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.
