Impact of Catheter Ablation on Sleep quality and Relationship Between Sleep Stability and Recurrence of Paroxysmal Atrial Fibrillation After Successful Ablation: 24-hour Holter-Based Cardiopulmonary Coupling Analysis. J Am Heart Assoc 2020; 23: e017016. DOI: 10.1161/JAHA.120.017016
Sleep fragmentation and sleep apnea are common in patients with atrial fibrillation (AF). The aim was to investigate the impact of radio-frequency catheter ablation (RFCA) on sleep quality in patients with paroxysmal AF and the effect of a change in sleep quality on recurrence of AF.
Sleep quality estimated by an ECG-based analysis was improved after RFCA in patients with paroxysmal AF. The recurrence rate of AF was significantly lower in patients who had unstable sleep before RFCA. The worse the sleep quality before RFCA, the less likely the recurrence of AF. This could plausibly be the result of an improvement in sleep quality.
RFCA has the additional benefit of improving sleep quality beyond rhythm control. Sleep quality assessment before RFCA may provide a risk marker for recurrence after RFCA in patients with paroxysmal AF who undergo RFCA.
