Alternating QRS Morphologies and PR Intervals After Transcatheter Aortic Valve Replacement

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...
