Ablation of premature ventricular contraction triggering ventricular fibrillation in a patient with early repolarization syndrome

摘要

Early repolarization syndrome is associated with an increased risk of arrhythmic death caused by ventricular fibrillation (VF). VF is usually initiated by premature ventricular contractions (PVCs), and PVCs commonly arise from Purkinje system, the ventricular outflow tract, and papillary muscles. We report the case of a patient with J wave syndromes and recurrent VF, triggered by PVCs originating from the tricuspid annular region. VF was successfully suppressed by catheter ablation of the triggering PVCs, and there has been no recurrence of VF during a follow‐up period of 6 months.
