Fitbit wearables can now passively monitor a user’s blood flow for irregular heart-beat rhythms.
The US Food and Drug Administration has approved Google’s Fitbit photoplethysmography (PPG) algorithm to identify atrial fibrillation (AFib). Google says the AFib detection feature will be coming soon to some of its devices that can measure heart rates. It assesses the user’s heart rhythm in the background while they’re still or asleep, according to Google. Fitbit says AFib detection is compatible with its Sense, Versa, Versa Lite, Charge 4 and Inspire 2 devices.
