Conditions

paroxysmal atrial fibrillation

Interventions

group A:Pulmonary antrum radial-linear ablation group: six to eight radial-linear lesions were created with RF ablation from pulmonary vein orifice to pulmonary vein –left atrium junction( the site wh

Group B:Circumferential pulmonary vein ablation group: the conventional circumferential pulmonary vein ablation was performed only. The procedural end point was bi-directional block between pulmonary
