Variable morphology wide complex rhythm: what is the etiology?

Ann Noninvasive Electrocardiol. 2008 Jan;13(1):92-4. doi: 10.1111/j.1542-474X.2007.00206.x.

Abstract

We report a case of an infant who developed transient complete heart block following aortic and mitral valve surgery. In the course of his recovery, he developed a variable morphology wide complex rhythm with intermittent narrow complex beats. Review of his initial postoperative electrocardiogram (ECG), which demonstrated a right bundle branch block, helped to clarify the rhythm.
