This study aimed to identify effective antiarrhythmic drugs (AADs) during the blanking period and to examine the association between AAD efficacy and long\u2010term outcomes.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>Initially, 497 patients who underwent catheter ablation for AF between April 2017 and December 2022 were included. Among these, patients who experienced ERAT after their first AF ablation were analyzed for this retrospective study. During the blanking period, the effectiveness of three AAD regimens, pilsicainide, bepridil, and bepridil plus aprindine, was compared. Patients were followed for 2\u2009years after AAD discontinuation and stratified according to late recurrence.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      Among the 75 patients analyzed, ERAT was suppressed in 29.6% (8\/27) with pilsicainide, 38.1% (8\/21) with bepridil, and 77.8% (21\/27) with bepridil plus aprindine (\n                      <jats:italic>p<\/jats:italic>\n                      \u2009=\u20090.0009). Among patients without late recurrence, ERAT suppression was higher with bepridil\u2010based regimens: pilsicainide, 27.8% (5\/18); bepridil, 66.7% (6\/9); and bepridil plus aprindine, 89.5% (17\/19) (\n                      <jats:italic>p<\/jats:italic>\n                      \u2009=\u20090.0006).
