The Apple Watch Series 4 introduced a built-in ECG, allowing users to monitor their hearts for an irregular pulse. In research issued as part of the Apple-Stanford Medicine Apple Heart Study, it seems that the Apple Watch can detect a variety of different arrhythmias than first thought.The study, published in the American Heart Association Journal and first reported by MyHealthyApple, the Apple Watch’s irregular pulse detection algorithm has a positive predictive value of 0.84 for the identification of AFib in an initial analysis from November 2019. In a new second analysis, researchers examined participants of the Apple Heart Study that had received an ambulatory ECG patch after an index irregular pulse notification.
