Startup claims Apple Watch + AI can detect heart conditions
Using the Apple Watch and artificial intelligence, health startup Cardiogram reports they could detect a type of abnormal heart rhythm with 97% accuracy by analyzing data from the watch's heart sensor.
Why it matters: Atrial fibrillation affects an estimated 2.7 million people in the U.S. and is a predictor of heart attack, stroke and dementia. The abnormal rhythms are the cause of 1 in 4 strokes. In many cases, there are no symptoms and though people are monitored for weeks to try to catch the abnormalities, months can pass before they occur, so they are missed. The researchers hope by continuously monitoring for abnormalities they can lower the number of undiagnosed cases.
