Fitbit has received clearance from the US Food and Drug Administration for its atrial fibrillation detection algorithm, Google said Monday.
The technology, which Google says will be coming soon to a range of heart-rate-enabled devices, passively assesses your heartbeat rhythm. If it comes across anything that suggests AFib, it will then alert you through the Irregular Heart Rhythm Notifications feature.
Google earned clearance for the AFib-detecting technology partly because of a 2020 Heart Study which monitored over 455,000 participants for five months. The study found that Fitbit detected and correctly identified AFib episodes 98% of the time, when compared to ECG patch monitors.
