Pulmonary Vein Isolation Using the First-Generation Cryoballoon Technique in Chinese Patients

BackgroundCryoballoon ablation is an alternative for the treatment of atrial fibrillation (AF). We assess the relationship among pulmonary vein (PV) electrophysiology, balloon temperature, and persistent PV isolation (PVI), and report procedural properties, safety, and efficacy of this technique in a Chinese center for the first time.
