Brief Summary:
It's a multi-center, prospective, randomized, controlled clinical trial of cryoballoon versus radiofrequency ablation for paroxysmal atrial fibrillation.

Condition or disease Intervention/treatment Phase
Atrial Fibrillation Procedure: cryoballoon ablation Procedure: radiofrequency ablation Not Applicable

Detailed Description:
The hypothesis of this study is that pulmonary vein isolation with cryoballoon ablation is not inferior to radiofrequency ablation with 3D mapping with respect to clinical safety and efficacy.
