Abstract

A woman with ischemic cardiomyopathy presented with recurrent syncope. Electrocardiogram showed complete heart block and torsade de pointes (TdP) secondary to amiodarone, recently started for paroxysmal atrial fibrillation. We describe a novel application of His bundle pacing that suppressed TdP and corrected the underlying left bundle branch block. (Level of Difficulty: Intermediate.).
