While Fitbit trackers and smartwatches are a terrific way to monitor your progress toward better health, they have also added the ability to detect AFib, which can alert you to potential cardiac issues. Fitbit’s irregular heart rhythm notifications have now amassed over 2 million users in just a few months since its release.

WHAT DO THE IRRITATED HEART RHYTHM NOTIFICATIONS FROM FITBIT MEAN? Fitbit devices’ Irregular Heart Rhythm Notifications feature was initially introduced in April 2022. Fitbit’s version of AFib detection, which analyzes sensor data to look for indicators of atrial fibrillation and other irregular heart rhythms, is implemented in this function.

AFib is a condition of the heart where the heart beats irregularly. According to John Hopkins Medicine , it’s a dangerous disorder that puts persons who have it at a five times higher chance of having a stroke.

Fitbit uses a unique PPG (photoplethysmography) algorithm that was approved by the US FDA in April to find symptoms of AFib. Your wrist’s blood vessels’ volume variations can be measured by the algorithm.

When compared to conventional patch ECG monitors, Fitbit claims that the PPG algorithm could correctly identify AFib episodes 98% of the time. This certainly presents a lot more practical way to track the data. If these symptoms are found while the person is lying still or asleep, alerts for AFib are delivered.

THE FITBIT AFIB ALERTS ARE USED BY MORE THAN 2 MILLION PEOPLE. Fitbit said to 9to5Google that as of June 2022, over 2 million people had signed up to receive notifications of abnormal heartbeats. Upon enrollment, a user’s compatible Fitbit device begins monitoring for indications of AFib.

Given that the feature is accessible on so many different devices, it is simple to understand why it has gained popularity so quickly. Irregular Heart Rhythm Notifications are supported by Fitbit Sense, Versa 3/2/Lite, Inspire 2, Luxe, and Charge 3/4/5.

However, there is obviously far more space for Fitbit customers to sign up with this option. Fitbit had 11 million sold devices and around 31 million active users in 2020, according to Statista .

There is a restriction to how many people can currently adopt the function because it is only available in the United States.
