Background: Early diagnosis and treatment of sleep apnea in patients with atrial fbrillation (AF) is critical. The WatchPAT (WP) device was shown to be accurate for the diagnosis of sleep apnea; however, studies using the WatchPAT device have thus far excluded patients with arrhythmias due to the potential effect of arrhythmias on the peripheral arterial tonometry (PAT) amplitude and pulse rate changes. Purpose: To examine the accuracy of the WP in detecting sleep apnea in patients with AF. Patients and Methods: Patients with AF underwent simultaneous WP and PSG studies in 11 sleep centers. PSG scoring was blinded to the automatically analyzed WP data. Results: A total of 101 patients with AF (70 males) were recruited. Forty-six had AF episodes during the overnight sleep study. A significant correlation was found between the PSG-derived AHI and the WP- derived AHI (r=0.80, p Conclusion: WP can detect sleep apnea events in patients with AF. AF should not be an exclusion criterion for using the device. This finding may be of even greater importance in the era of the COVID19 epidemic, when sleep labs were closed and most studies were home based.

Introduction Sleep apnea is a common sleep disorder increasingly recognized as a risk for cardiovascular disease. Atrial fbrillation (AF) is the most common cardiac arrhythmia. AF is associated with significant [...]
