Summary

This study tests whether a connected watch can better detect returning atrial fibrillation (an irregular heartbeat) in 106 adults who had heart surgery and developed a temporary irregular rhythm. Participants will wear the watch for 12 months, and doctors will compare how well it catches rhythm problems versus standard checkups at 3, 6, and 12 months. The goal is to see if the watch helps guide treatment and reduce complications.
