摘要
It has been demonstrated that pulmonary veins （PV）play an important role in the initiation and perpetuation of paroxysmal atrial fibrillation （PAF）.1-5 Therefore, PV isolation has become the cornerstone for catheter ablation in the majority of these AF patients.3-5 In addition, ectopic foci in the non-PVs areas, such as superior vena cava（SVC）,
