Apple watch could save lives by detecting irregular heartbeats

Local News

A new study shows Apple watches may be able to save lives by their ability to detect irregular heart rates.

Researchers looked at pulse data collected by the watch’s heart rate monitor from 400,000 participants. They send electrocardiogram patches to wearers who showed irregular pulses. About a third of them turned out to have atrial fibrillation, a potentially fatal condition that contributes to 130,000 deaths in the US each year.

Researchers say false positives are a concern in these types of tests, and the Apple watch returned those about 29% of the time.
