Catheter ablation of atrial fibrillation (AF) has become a first‐line therapeutic option. Pulmonary vein isolation (PVI) has become an effective approach for paroxysmal AF ablation. The PVs may play an important role in not only the initiation but also the maintenance of AF. Therefore, many studies regarding the electrophysiological properties of the PVs have been reported. AF is frequently triggered by ectopic beats from the PVs. However, all the ectopic beats from the PVs do not always trigger AF. In this issue of the journal, Kawai et al. suggested the electrophysiological determinant factors of AF initiation from the PVs.
