Disrupted Sleep and Concurrent Ectopy or Atrial Fibrillation
University of California, San Francisco
100 participants
Dec 15, 2025
INTERVENTIONAL
Conditions
Summary
Whereas the available evidence mostly supports chronic sleep disruption as a risk factor for incident AF, less is known about the near-term risk of a discrete atrial fibrillation (AF) episode following a night of disrupted or poor-quality sleep. This prospective, randomized, case-crossover study aims to examine the acute effects of sleep disruption on clinically relevant cardiac ectopy pertinent to AF.
