Heart Rate Variability
Heart rate variability refers to millisecond variations between heart beats. HRV is a non-invasive measurement of the autonomic nervous system (the body's main control center) and is widely considered the most comprehensive biomarker of health and fitness.
By measuring your autonomic nervous system, HRV reveals how your body responds to exercise, illness, treatment, recovery, inflammation, stress, mental health, and every lifestyle choice you make.
Heart rate variability is an umbrella term that describes general variability between heart beats; there are a number of specific HRV metrics used to analyze different features and patterns in heart rate variability that are correlated with different physiological states. Here is a description of our HRV score.
The HRV Score is based on RMSSD and scaled to a meaningful 1-100 score. This is an absolute indicator of Autonomic Nervous System health and strength.
