Background Early recurrences of atrial arrhythmias (ERAAs) after ablation may require therapeutic intervention. The optimal medical therapy that prevents ERAAs requires clarification. This study aimed to compare the incidence of ERAAs between patients who received or did not receive bisoprolol transdermal patches (BTPs) at 3 months postablation. Methods This single‐center retrospective study enrolled 203 consecutive patients with paroxysmal atrial fibrillation (AF) who had undergone their first ablation, comprising 59 in the BTP group and 144 in the non‐BTP group. Follow‐up assessments were conducted monthly for 3 months. We evaluated the incidence of ERAAs. Results During the initial 1‐week observational period, the rate of ERAAs was lower in the BTP group (5.0%) than that in the non‐BTP group (18.8%) ( P = .013). At 3 months postablation, the rate of ERAAs was lower in the BTP group (6.8%) than that in the non‐BTP group (25.7%) ( P = .002). The cumulative freedom from ERAAs was significantly lower in the BTP group than in the non‐BTP group (log‐rank: P = .003). Administering BTPs was an independent factor that protected against ERAAs (odds ratio 0.181, [95% confidence interval 0.059‐0.559], P = .003). Conclusion BTPs may prevent ERAAs after ablation.
