Smartwatch could spot silent heart rhythm problem after surgery
NCT ID NCT05573633
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tests whether a smartwatch (Withings ScanWatch) can diagnose atrial fibrillation that occurs after heart surgery better than standard monitoring. About 324 adults who had on-pump heart surgery will either use the smartwatch or receive usual care. The goal is to catch silent, symptom-free episodes that might otherwise be missed, potentially reducing the risk of stroke and other complications.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- Active substance
- smartwatch (Withings ScanWatch) with 1-lead ECG
- What this could lead to
- If successful, this could show that smartwatches are a reliable way to catch hidden heart rhythm problems after surgery, potentially preventing strokes and other complications.
- What could go wrong
- This is a single-center trial with 324 participants, so results may not apply to all patients. The smartwatch may miss some episodes or cause false alarms, and it requires patients to be able to use it correctly.
