Researchers from Stanford University’s School of Medicine presented results from a giant study sponsored by Apple Inc. that showed the Apple Watch can sometimes spot patients with undiagnosed heart-rhythm problems, without producing large numbers of false alarms.
The Apple-sponsored trial enrolled 419,297 people and was one of the largest heart-screening studies ever. The study, details of which are being presented today at the American College of Cardiology conference in New Orleans, used the watch’s sensors to detect possible atrial fibrillation.
