Bundle branch block: ECG quiz video

Plays from YouTube when you click. Nothing loads from YouTube before that.

A 26-second clip of the Patient Simulator monitor. The rhythm name is never on the screen: the video asks the question, gives a hint, counts down five seconds and then gives the answer.

Hint

What rhythm is this? Look at the width and shape of the QRS.

Answer

Bundle branch block. Sinus rhythm with a wide, notched QRS and the T wave pointing the other way. Left or right needs leads V1 and V6.
