Read our Atrial Fibrillation research guide →After heart surgery, some patients develop an irregular heart rhythm called atrial fibrillation. This study is testing whether a connected smart watch can help doctors detect and monitor this condition more effectively than standard heart rhythm checks alone. The goal is to see if the watch helps keep patients safer and gives doctors better information to guide their care.
Irregular heart rhythm after surgery is common and can be serious, but it's not always easy to catch with standard check-ups. This study exists to see if a smart watch worn at home can detect these problems earlier and help doctors treat patients more effectively.

You will wear a connected smart watch that monitors your heart rhythm at home. Alongside standard heart check-ups, you'll use the watch to record your heart rhythm regularly over 12 months after your surgery. The watch sends the information to your doctors, who can see your results and adjust your care if needed. You'll need to attend follow-up appointments as directed by your surgical team.
