2022: Announcement of arrhythmia recognition software by wearable devices

On April 11, 2022, Fitbit announced PPG (photoplethysmography) technology, which is software for recognizing arrhythmia using wearable devices.

Detection of arrhythmia or atrial fibrillation (AF) is becoming an increasingly important function in wearable health-focused devices. According to Google (owner of Fitbit) on its blog, about 33.5 million people in the world suffer from this form of irregular heartbeat, which can increase the risk of stroke by about 5 times. These devices quickly evolved from simple step counters to important medical tools.

Fitbit announced PPG (photoplethysmography) technology, which is a software for recognizing arrhythmia using wearable devices.

The company notes that further development became possible thanks to the results of the 2020 Heart Study, in which about 450 thousand people were observed over five months. It notes 98% effectiveness for AFib episodes compared to specially designed ECG patches.

Fitbit describes the technology as follows:

When your heart beats, the tiny blood vessels throughout the body expand and narrow depending on the change in blood volume. Fitbit's PPG optical heart rate sensor can detect these volume changes directly from your wrist. These measurements determine the heart rate, which the detection algorithm analyzes for disorders and potential signs of atrial fibrillation.

The technology provides a more consistent approach to detecting atrial fibrillation, as opposed to periodic checks that are still available through the Fitbit app. More constant monitoring allows the device to check when the user is in a state of rest or sleep, which is often the optimal time to detect heart rate disorders.

Fitbit reports that the development will be introduced into heart rate monitoring devices "In the near future" for consumers in the United States. The addition of this technology should make it widely available in a wide range of prices for company wearables.[1]
