Heart Rate Variability
The degree of fluctuation in the time intervals between consecutive heartbeats. It is an important physiological indicator for assessing the balance of the autonomic nervous system; higher HRV generally reflects parasympathetic activity and good physical recovery.

Timeline (last 90 days)
Examples of physiological indicators include heart rate variability and galvanic skin response; examples of behavioral indicators include typing rhythm, mouse trajectories and pause patterns; examples of subjective scales include NASA-TLX.
Individual baseline differences in HRV are extremely large, and age, genetics, and daily condition all significantly affect readings.
Heart rate variability (HRV) refers to the small fluctuations in the time intervals between consecutive heartbeats, reflecting the autonomic nervous system's ability to regulate the heart, and higher HRV is generally associated with better cardiovascular health.
Higher heart rate variability (HRV) generally indicates a greater capacity for flexible regulation of the autonomic nervous system.
临床研究表明，低HRV与焦虑、抑郁、心血管疾病风险升高显著相关
