But in recent years, companies have launched apps and wearable heart rate monitors that do something similar. The accuracy of these methods is still under scrutiny, but the technology is improving.

Sep 13, 2021 · The Fitbit smartwatches and trackers will monitor the heart rate and extract the Heart Rate Variability (HRV). The HRV corresponds to the millisecond differences between two consecutive heartbeats. The HRV will change during the different sleep cycles and, when combined with the movement detector sensors, will accurately detect the sleep stage. HRV is the variations, not the absolute time between each heart beat. If HRV is 0, the time between each heartbeat would be exactly the same. The body will constantly throttle the HR up or down when additional oxygen is needed etc. A large HRV means the system is working great at quickly adjusting HR as needed.
