Can a sleep machine keep your heart in rhythm?
NCT ID NCT04519489
First seen Jun 25, 2026 · Last updated Jun 26, 2026 · Updated 1 time
Summary
This study looked at whether using a positive airway pressure (PAP) machine at night can reduce the return of atrial fibrillation (an irregular heartbeat) in people who also have obstructive sleep apnea. About 129 participants with both conditions were assigned to receive either standard heart care plus PAP therapy or standard care alone. The goal was to see if treating sleep apnea helps keep the heart in a normal rhythm after procedures like ablation or medication.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
Positive airway pressure (PAP) therapy device (Philips DreamStation) with telemonitoring (Philips EncoreAnywhere)
What this could lead to
If successful, this could show that treating sleep apnea with PAP therapy helps prevent atrial fibrillation from coming back after standard heart rhythm treatments.
What could go wrong
The study was terminated early, so results may be incomplete. It is also unclear how well patients will stick to nightly PAP therapy, which is crucial for effectiveness.
