«A large-scale clinical trial of Fitbit’s pulse-tracking algorithm showed some success in spotting the hidden signs of atrial fibrillation, demonstrating the capability of smartwatches and fitness trackers as a frontline screening device for the potentially dangerous heart condition.

After launching the study in May 2020, more than 455,000 Fitbit users signed up to participate in less than five months, including about 13% who were over 65—an age group at higher risk for the irregular heartbeat and its related strokes.»
