Sleep Quality Change After RFCA In Paroxismal Atrial Fibrillation & Relation of Sleep Stability To the Recurrence: 24 – hour Holter – based Cardiopulmonary Coupling Analysis.

Sleep instability is highly prevalent in patients with cardiovascular disease (CVD) and evidence supports a casual association of sleep instability with CVD> We investigated the impact of radiofrequency catheter ablation (RFCA) on sleep instability in patients with paroxysmal atrial fibrillation (pAF) and the effect of sleep stability on recurrence of atrial fibrillation.
Sleep quality was improved after RFCA in patients with pAF. Furthermore, the recurrence rate was significantly lower after RFCA in patient who had pre-RFCA sleep instability (LFC≥50.3%).
These results suggest that RFCA can influence sleep quality and sleep quality assessment, and that analyzing routine 24-hr Holter studies can be a predictable marker of recurrence after RFCA in patients with pAF.
