The purpose of the study is to determine if, in people with sleep apnea who have undergone cardioversion therapy for atrial fibrillation, the recurrence rate of atrial fibrillation is affected by sleep apnea treatment.

    Positive airway pressure therapy effectively treats obstructive and central sleep apnea.
Detailed Description:

sleep apnea is a common disorder which is increasingly implicated in the pathogenesis of cardiovascular disease. Observational data suggest that sleep apnea may play a role in the development of atrial fibrillation (AF), and may even predispose to recurrence of AF following electrical cardioversion (DCCV). Because of biases and confounders inherent to observational studies, we propose a randomized clinical trial to assess the effects of treatment of sleep apnea in subjects with AF treated with DCCV. Following polysomnography, subjects with sleep apnea will be randomized to positive airway pressure (PAP) or usual medical care and followed for up to one year to compare a primary outcome of AF recurrence rate.
