Radiofrequency catheter ablation of atrial fibrillation initiated by pulmonary vein ectopic beats.
Ectopic beats from the pulmonary veins (PVs) have been demonstrated to initiate atrial fibrillation (AF). This article describes the conceptual approach to mapping, interpretation of different electrograms, and ablation of AF initiated by PV ectopic beats.
