12/24/2023 0 Comments Apple watch heart monitor”These are people who may stand to benefit from knowing their condition,” he says, since they could then take preventive measures or get treatment to stability their abnormal heart rate. With further confirmation, the app could help identify AFib in people who are not even aware of their condition. But it showed that in a group of people with varying degrees of vulnerability to AFib, an algorithm used in a smartphone-based device could, relatively accurately, pick up the condition. Turakhia notes that the study doesn’t necessarily suggest that the Apple app could be used to definitively screen everyone for AFib - yet. ![]() Because AFib is episodic, and doesn’t occur continuously, this allowed the researchers to compare when the app detected abnormal heart rhythms and when the gold-standard ECG did. These people were then asked to contact the study team, which sent them ECG patches to wear on their chest for up to seven days while still using the app. Over a period of nearly four days, the watch notified 0.5% of this group of potential abnormal heart rhythms. In the NEJM study, the scientists reported results from nearly 420,000 people who already owned Apple Watches and volunteered to participate. 13 in the New England Journal of Medicine, they report that the app’s alerts matched up with electrocardiography, or ECG readings (the gold standard for detecting atrial fibrillation) 84% of the time. Early results of the research project, known as the Apple Heart Study, were presented at the annual meeting of the American College of Cardiology last spring. ![]() Researchers at Stanford University have been working with Apple to study how accurately the tech giant’s app could detect AFib in a general population.
