Researchers at the University of California, San Francisco (UCSF) and a mobile health app Cardiogram revealed results of a joint study which shows that Apple Watch’s sensors can differentiate normal heart rate between atrial fibrillation with 97% of accuracy. Atrial fibrillation is an abnormal heartbeat that can increase risk of blood clots, stroke, heart failure and other heart-related complications. The study was conducted on 6,158 persons by collecting their heart rate and electrocardiogram data by relying on Apple Watch.
Cardiogram uses Apple Watch’s built-in heart sensor to provide you with info about your heart health. It shows when a user is very stressed out by tracking his or hers heart rate.
Director of clinical research for the Division of Cardiology at UCSF Gregory M Marcus stated: “While mobile technology screening won’t replace more conventional monitoring methods, it has the potential to successfully screen those at an increased risk and lower the number of undiagnosed cases of AF.”
