Electrophysiological characteristics and catheter ablation of symptomatic focal premature atrial contractions originating from pulmonary veins and non‐pulmonary veins

Abstract

Frequent PACs originating from PVs were associated with increased incidence of atrial fibrillation compared with PACs originating from non-PVs. Catheter ablation yields a satisfactory success rate and could be a good choice for eliminating symptomatic, frequent, and drug-refractory PACs.
