Multifocal Purkinje-related premature contractions and electrical storm suppressed by quinidine and verapamil in a case with short-coupled ventricular fibrillation.

Abstract

In some cases with idiopathic ventricular fibrillation, short-coupled premature ventricular contractions (PVCs) initiate fatal arrhythmia, which has recently been proposed as short-coupled ventricular fibrillation (SCVF). In the present case of SCVF, catheter ablation for trigger PVCs originating from the His-Purkinje system in both ventricles caused transient complete atrioventricular block, and a combination of quinidine and verapamil suppressed ventricular tachyarrhythmia. <Learning objective: In some cases with short-coupled ventricular fibrillation, a combination of quinidine and verapamil can suppress fatal ventricular tachyarrhythmia.>.
