RFCA of triggering PVCs eliminates VF in a patient with early repolarization syndrome.
Radiofrequency catheter ablation may be a useful strategy for eliminating ventricular fibrillation triggered by PVCs from the right ventricular outflow tract in patients with early repolarization syndrome.
Ventricular fibrillation (VF) triggered by premature ventricular contraction (PVC) most frequently originates from the His-Purkinje system and right ventricular outflow tract (RVOT) in patients with idiopathic VF. Radiofrequency catheter ablation (RFCA) of triggering PVCs is reportedly useful for the successful elimination of VF.1–3
