Abstract
AbstractAccelerated idioventricular rhythm (AIVR) originating from the right bundle branch (RBB) (RBB‐AIVR) is a rare ventricular arrhythmia. We delineated RBB and myocardial activation separately during RBB‐AIVR, which revealed the spatial relationship of the AIVR origin, preferential pathway, and breakout site. Radiofrequency ablation to the preferential pathway successfully eliminated this arrhythmia.
