The FDA’s green lights are Fitbit’s AFib detection algorithm designed for long -term detection.

This morning Fitbit secured FDA approval for its long wait photoplethysmography atrial fibrillation (AFib) diagnostic algorithm. The algorithm will be part of Fitbit’s new Irregular Heart Rhythm Notification feature, designed to alert users to possible AFib.

The technology can run passively on Fitbit wearers and monitor the heart rate when a person is asleep or not moving. Users with the supposed AFib will receive a message stating that they see a health care professional.

“When your heart beats, small blood vessels increase in your body and are blocked due to changes in blood pressure,” the Fitbit team wrote on a blog announcing the concession.

“Fitbit’s PPG optical heart-rate sensor can detect these sound changes from your hand. These measurements determine your heart rate, and then the detection algorithm records for errors and symptoms. or atrial fibrillation. “

Users can use Fitbit’s ECG app for a more detailed evaluation. This new permission provides an alternative, using PPG-based algorithm for long-term heart rate analysis. According to the company’s release, the new model and algorithm will soon be available in the US

In March, the company announced that it had submitted the AFib detection algorithm to the FDA. When the business was announced the Fitbit Heart Study, released in 2020 with results released late last year. The study, reported at the American Heart Association Scientific Sessions, found that the Fitbit PPG sensor was able to accurately detect AFib components 98% of the time.

THE GREAT WORK

According to the Mayo Clinic, AFib can increase a patient’s risk of stroke, heart attack and other heart problems. The health system shows that AFib itself does not usually kill, but it needs to be taken care of to prevent stroke.

Fitbit is promoting its technology as a way to help users see what AFib is capable of.

“AFib is a common heart disease that affects about 33.5 million people worldwide, and people with AFib have five times the rate of stroke.” Fitbit wrote in a release.

THE GREAT WORK

It’s no secret that businesses are looking for ways to increase their access to heart health. In 2018, Apple became the first consumer technology Industry to roll out an ECG model.

Fitbit quickly followed suit in 2020, level US and European regulatory approval for its Fitbit Sense to scan the heart and detect atrial fibrillation. Other companies including Withings and Samsung have also integrated ECG features.
