Can a sleep machine tame a fluttering heart?
NCT ID NCT04513483
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looked at whether using a CPAP machine at night can reduce episodes of atrial fibrillation (a type of irregular heartbeat) in people who also have obstructive sleep apnea. Twenty-five adults with both conditions were enrolled. Half used CPAP while the other half were observed. The goal was to see if CPAP lowers the time spent in AFib and improves quality of life.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- Active substance
- continuous positive airway pressure (CPAP) device
- What this could lead to
- If successful, CPAP could become a standard add-on treatment to help control atrial fibrillation in patients with sleep apnea.
- What could go wrong
- This is a very small, early-stage study with only 25 participants. Results may not apply to everyone, and CPAP may not significantly reduce AF burden.
