Does Fitbit detect irregular heartbeats?

Yes, Fitbit does indeed detect irregular heartbeats! The Fitbit trackers are equipped with an advanced heart rate monitoring technology that can track and detect any changes in your cardiac rhythm. This feature is especially helpful for those who may have some sort of arrhythmia or atrial fibrillation (AFib).

Using the latest optical sensors and LED lights, the device is able to measure blood velocity through your wrist to detect a change in cardiac rhythm. After analyzing this data, it can notify you if there’s an irregularity detected. It even stores your heart rate data so you can monitor any fluctuations over time.

In addition to tracking heartbeat changes, some models trigger notifications when your resting heart rate goes above or below a set threshold - making them ideal for athletes and people concerned about their health. If a higher-than-normal reading is recorded on the tracker three times in the same day, then it will send out an alert asking you to visit a doctor immediately.

Overall, Fitbits are capable of reliable detection of irregular heartbeats and other conditions that could be detected sooner rather than later with these devices - enabling users to take action as quickly as possible should something be amiss with their hearts.
