Pacemaker algorithm could spot sleep apnea without extra tests
NCT ID NCT02751021
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested whether a special algorithm in a pacemaker can accurately diagnose sleep apnea in people with heart problems. Researchers compared the pacemaker's readings to a standard overnight sleep test in 66 participants. They also looked for a link between sleep apnea severity and a hormone called aldosterone.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- What this could lead to
- If successful, this could offer a simpler, more accessible way to diagnose sleep apnea in people with pacemakers, without needing a separate sleep study.
- What could go wrong
- This is a small, completed study with only 66 participants, so results may not apply to everyone. The algorithm may not be as accurate as standard tests.
