Key inclusion criteria
1)Symptomatic drug-refractory AF, referred to kanazawa medical center between September 2014 and August 2015 for RF catheter ablation for their first procedure.
2)Patients who underwent anatomical ipsilateral PVI and who were assessed for dormant conduction (DC) by an intravenous bolus of adenosine.
Key exclusion criteria
We excluded cases that required RF application in carina other than the PV antrum to achieve PV isolation.

Other related information
FTI, maximum CF, average CF, minimum CF, RF duration, and RF power were obtained for each ablation point.
The FTI for each ablation point was divided by the wall thickness of the PV atrium segment where the ablation point was located to calculate the ablation FTI required for every 1 mm of wall thickness (FTI/wall thickness).
