Smartwatches vs. implants: a cheaper way to catch hidden stroke causes?

NCT ID NCT06832579

First seen Nov 19, 2025 · Last updated May 08, 2026 · Updated 25 times

Summary

This study tests whether a smartwatch (Apple Watch or PulseOn) can detect hidden atrial fibrillation (AF) in 84 stroke survivors who already have an implanted heart monitor. Participants wear the watch for 12 weeks, and the watch alerts them if it senses an irregular pulse. The goal is to see how well the watch catches AF episodes compared to the gold-standard implant. If successful, this could offer a less invasive and cheaper way to monitor stroke patients for AF.
