Extended Cardiac Monitoring in Patients with Severe Sleep Apnea and no History of Atrial Fibrillation (The Reveal XT-SA Study)

Atrial fibrillation (AF) is a risk factor for ischemic stroke and reported to be associated with severe obstructive sleep apnea (OSA). The aim of this study was to determine the occurrence of newly detected AF in patients with severe OSA and no prior history of AF. Prospective observational study included patients with severe OSA (Apnea-Hypopnea Index (AHI) ≥ 30) and no history of AF. Primary outcome was detection of AF lasting ≥10 s. Patients were subjected to 2 24-hour Holter monitors, and if no AF was detected, implanted with a Medtronic Reveal XT implantable loop recorder (ILR).
