Apple Heart Study

The Apple Heart Study app uses data from an Apple Watch to identify irregular heart rhythms, including those from potentially serious heart conditions such as atrial fibrillation. Apple is conducting this research study in collaboration with Stanford Medicine to improve the technology used to identify irregular heart rhythms. Early diagnosis and treatment of irregular heart rhythms may prevent serious health issues.

The Apple Heart Study is currently closed to new participants. Participants who have already enrolled should remain in the study until it concludes. Visit Stanford Medicine for more information on the study.

How It Works

If a participant in the Apple Heart Study has an irregular heart rhythm observed they will receive a notification on their Apple Watch and within the Apple Heart Study app on their iPhone. Through the app they will be able to connect with a doctor who will further explain the notification and discuss next steps.
