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.
