Summary

This study looks at better ways to find hidden atrial fibrillation (an irregular heartbeat) in people who have had a stroke. About 337 participants will use either a wearable patch for 72 hours or a handheld device three times a day to monitor their heart rhythm. The goal is to see which method catches more cases of atrial fibrillation, so doctors can prescribe blood thinners to prevent another stroke.
