Abstract

Abstract: Background: Catheter ablation improves physical activity in patients with atrial fibrillation (AF). However, continuous daily evaluation and time course of improvement in physical activity after ablation have not been fully assessed. This prospective study was conducted to evaluate the daily physical activities and changes in the physical performance in patients undergoing catheter ablation for AF by continuous monitoring of a portable accelerometer. Methods: Ten patients scheduled for catheter ablation for AF were fitted with a uniaxial accelerometer prior to and 6 months after the procedure. This study evaluated changes in daily steps, activity intensity, and activity duration. We also evaluated changes in activity intensity using a short version of the International Physical Activity Questionnaire (IPAQ). Results: The maximum daily steps significantly increased from baseline to postablation (baseline, 9, 232 [6, 716–11, 485]; after 1–3 months, 11, 605 [8, 285–14, 802]; and after 4–6 months, 11, 412 [8, 939–13, 808], p = .020). Similarly, Δ maximum‐mean daily steps increased significantly (baseline, 2, 431 [1, 199–6, 181]; after 1–3 months, 4, 674 [4, 164–6, 474]; and after 4–6 months, 4, 871 [3, 657–6, 117], p = .014). These improvements were more pronounced in patients with paroxysmal and symptomatic AF. The total IPAQ score significantly improved from baseline to after 6 months ablation (from 1, 170 [693–3, 930] to 4, 312 [1, 865–6, 569], p = .037). All patients were recurrence‐free from AF after ablation. Conclusions: The physical activity improved significantly even in the early phase following catheter ablation. The effect of suppressing AF on activity levels was apparent soon after the procedure.
