In addition, when paired with a wearable ECG patch monitor, the algorithm was 98 percent accurate in detecting AFib cases. Results of the trial were shared at the American Heart Association’s annual scientific sessions late last year, which showed that about one-third of those who received irregular heart rhythm notifications went on to be diagnosed with AFib. Fitbit says this is particularly useful for the heart-monitoring technology since AFib is often best spotted when the body is at rest.įitbit validated the PPG algorithm in a large-scale clinical study involving more than 455,000 Fitbit users. The device has an impressive battery life of more than six days on a single charge. The algorithm is cleared to use in individuals 22 years of age or older who have no known history of irregular heart rhythm. ![]() The heart rate data is then analyzed by the PPG algorithm to detect any abnormalities and if any are found, the user is notified, who can then share the readings with a healthcare provider.įitbit said the PPG feature is compatible with a range of the company’s other heart rate enabled devices.

The Fitbit Sense 2 smartwatch is priced beginning at $300 and will begin to be shipped out towards the end of September. The new Fitbit Sense 2 contains sensors that can detect signs of atrial fibrillation through the company’s electrocardiogram (ECG) app and photoplethysmography (PPG) algorithm, which both have FDA clearance and CE marking.įitbit said all three new next generation devices “are even thinner and more comfortable, so you can wear them all day and night, and you don’t have to charge them every day.” While Inspire 3 and Versa 4 are fitness-focused, Fitbit said Sense 2 is the company’s most “advanced health-focused smartwatch” yet. ![]() Wearable technology giant Fitbit has revealed three new smartwatch models that it is adding to its collection this fall, including one that can detect signs of atrial fibrillation (AFib).įitbit made the reveal in a blog post, outlining the three new models - Inspire 3, Versa 4 and Sense 2.
