• ##® cardiac Cardiogram and the University of California , San Francisco have found that the Apple Watch is 97 % accurate in identifying abnormal heart rhythms when measured in conjunction with an AI - based algorithm . The researchers used data from 6,158 patients and trained a deep neural network to detect the 200 participants who suffered from paroxysmal atrial fibrillation , an abnormal heart rhythm . The study was designed to determine if the Apple Watch could detect oncoming strokes , of which around 25 % are caused by abnormalities in heart rhythm .
