Researchers with the Stanford University School of Medicine found in a study sponsored by Apple and released Saturday that the company’s smartwatches can detect irregular heart rhythms.

Of the approximately 400,000 participants using Apple Watches in the eight-month study, 0.5 percent, or about 2,000 people, were sent irregular heart rhythm notifications.

“The results of the Apple Heart Study highlight the potential role that innovative digital technology can play in creating more predictive and preventive health care,” Lloyd Minor, dean of the Stanford School of Medicine, said in a statement.
