ATP guide additional ablation.
Following successful PV isolation, intravenous ATP of 0.4 mg/body-weight-kg is rapidly is injected, and dormant LA-PV conduction is evaluated. If dormant LA-PV conduction is unmasked, then additional radiofrequency energy applications are delivered to the conduction gaps until disappearance of dormant LA-PV conduction.
Antiarrhythmic drug (AAD)
Following successful ablation, AAD (Vaughan Williams class I or III) is administered for 90 days. The recommended drugs are flecainide, propafenone, sotalol and amiodarone, but the final choice of drug and dosage is left to the discretion of the attending physician.

Control
Following successful ablation, AAD (Vaughan Williams class I or III) including flecainide, propafenone, sotalol and amiodarone is not used during the period of 0 - 90 days.
Control
Following successful PV isolation, intravenous ATP is not administered.
