Apple Watch heart trial recruits 400,000 participants

November 2, 2018

The Apple Heart Study aims to determine if a mobile app that leverages Apple Watch’s optical sensor to analyse pulse rate data will be able to detect irregular heart rhythms that indicate atrial fibrillation.

Apple and Stanford Medicine carried out the trial enrolment via an iPhone app. The trial will now involve data collection and is expected to be completed early next year.

Stanford University School of Medicine dean Lloyd Minor said: “We hope this study will help us better understand how wearable technologies can inform precision health. These new tools, which have the potential to predict, prevent and manage disease, are finally within our reach.”
