Does obstructive sleep apnea associate with atrial fibrillation

Obstructive sleep apnea (OSA) is a disorder in which transient obstruction (complete or partial) of the airway during sleep causes loud snoring, oxyhemoglobin desaturation and frequent arousal. 1-4 OSA has been identified to relate to many cardiovascular diseases such as hypertension, coronary heart disease, heart failure, and cardiac arrhythmia. In this article, we attempt to discuss the association between OSA and atrial fibrillation (AF) while reviewing the recent data on OSA and AF.
