Alternating QRS Morphologies and PR Intervals After Transcatheter Aortic Valve Replacement

Alternating bundle branch block pattern on electrocardiogram (ECG) is a concerning finding with important prognostic implications. This ECG challenge explores the electrophysiological mechanism of a case of alternating bundle branch block with alternating PR intervals. (Level of Difficulty: Beginner...
