Aims Circumferential pulmonary vein isolation (CPVI) has been reported to account for 30% of atrial fibrillation (AF) recurrence after initial ablation, and (PV) re-connection accounts about 80% AF recurrence. There is no information in the literature whether early identification treatment acute PV conduction recovery during ablation an impact on subsequent clinical results. The objective investigate prevalence observation time paroxysmal AF, evaluate re-isolation
