Does Fitbit Measure Heart Rate

To determine your heart rate the optical heart rate sensor in your fitbit device flashes its green leds many times per second and uses light sensitive photodiodes to detect these volume changes in the capillaries above your wrist.

Does fitbit measure heart rate. Fitbit fitness trackers also measure the resting heart rate which means it even tracks heart rate when you are still calm awake and comfortable. The fitbit alta does not track heart rate though the fitbit alta hr does include a heart rate tracking feature. Many other fitbit trackers feature 24 7 heart rate monitoring including the versa. So all in all fitbit tracks your heart rate accurately.

Then your device calculates how many times your heart beats per minute bpm. A study commissioned by the plaintiffs legal team concluded fitbit purepulse trackers do not provide a valid measure of the user s heart rate and cannot be used to provide a meaningful estimate of a user s heart rate they found that the charge hr was off by an average of 15 5 bpm and the surge was off by an average of 22 8 bpm. Rather than taking a measurement by heart rate while you wake up first this device is actually programmed to figure out your typical resting pulse rate when you re sleeping.
