Fitbit currently provides irregular heart rhythm notifications on some wearables in the US, allowing users to get a heads-up on atrial fibrillation (Afib). It has taken some time, but the company has finally announced that the feature is now available in more regions.
The current list of markets is as follows:
For compatible devices, Fitbit says irregular heart rhythm notifications are supported on the Sense, Sense 2, Versa Lite, Versa 2, Versa 3, Versa 4, Charge 3, Charge 4, Charge 5, Lux, Inspire 2 and Inspire 3 . So you are bound to find a wearable that supports this feature in your market.
The feature can be accessed through the Assessment section of the Fitbit app and monitors your heart rhythm while you sleep to check for signs of Afib. It is a condition characterized by an irregular heart rate, often associated with an increased risk of blood clots, heart attack, and stroke.
