Heart Rate Variability Trending

Meaning

Heart Rate Variability (HRV) Trending is the longitudinal, time-series analysis of the beat-to-beat variation in heart rhythm, serving as a dynamic, non-invasive biomarker for Autonomic Nervous System (ANS) function. Tracking HRV over days, weeks, and months provides a clinical metric for the body’s cumulative stress load, recovery efficiency, and physiological adaptation to training or lifestyle changes. Consistent trending is more informative than a single measurement, revealing the trajectory of an individual’s stress resilience and overall hormonal balance. This data is essential for modulating recovery and optimizing well-being.
