Sleep-disordered breathing (SDB) is a contributor to atrial fibrillation (AF) and the treatment of obstructive sleep apnea can reduce the recurrence of AF following catheter ablation. On the other hand, the impact of AF therapy and conversion to sinus rhythm is not fully understood. This is a case of a middle-aged man with SDB and persistent AF who exhibited improvement in SDB events, following sinus rhythm conversion. This supports the hypothesis that a bidirectional relationship between SDB and AF exist and highlights the importance of continuous monitoring of CPAP compliance, beyond improvement of daytime sleepiness.
