Quantify Mental Health and Autonomic Nervous System Function

What Is HRV? Heart Rate Variability measures the variation in time between heartbeats. Higher HRV indicates better stress resilience, cardiovascular fitness, and autonomic nervous system balance.

Metrics Captured:

HRV SDNN (Standard Deviation of NN Intervals)

  • Normal: >50 ms
  • Indicates: Overall cardiac health and autonomic regulation
  • Clinical Use: Stress assessment, cardiac risk stratification

RMSSD (Root Mean Square of Successive Differences)

  • Reflects: Parasympathetic (relaxation) nervous system activity
  • Clinical Use: Recovery from stress, sleep quality, mental health

Stress Index (Baevsky Method)

  • Scale: 1-10 (1 = relaxed, 10 = severe stress)
  • Based on: HRV analysis + heart rate patterns
  • Clinical Use: Mental health screening, burnout prevention

Pulse-Respiration Quotient (PRQ)

  • Ideal Ratio: ~5 (heart rate / respiration rate)
  • Indicates: Mind-body balance, autonomic coordination
  • Clinical Use: Traditional medicine integration, wellness optimization

Clinical Applications:

  • Mental Health
  • Cardiovascular
  • Integrative Medicine

Benefits for Practitioners:

  • Objective mental health data — Beyond subjective self-reports
  • Traditional medicine validation — Quantify holistic treatments
  • Preventive care tool — Identify stress before physical symptoms
  • Patient engagement — Visual feedback motivates behavior change
