Inclusion criteria

Inclusion criteria: We analyzed consecutive patients with AF who were referred to Toyama Prefectural Central Hospital in Japan between July 2021 and June 2023 for their first ablation procedures and underwent radiofrequency (RF) catheter ablation using CARTO 3 system (Biosense Webster, Inc.).

Design outcomes

Primary

Measure	Time frame
If the RPV was not isolated by circumferential ablation or reconnected during the waiting period, an exit map during mid RPV carina pacing was created. If the earliest site of the exit map was the RA, the patient was classified into the EC-ICB group. During the exit map, intra-atrial activation sequence and RPV-HRA time were evaluated.	—
