Your HRV is within the normal reference range, indicating adequate autonomic nervous system balance.
Your heart rate variability is critically low. HRV reflects the beat-to-beat variation in heart rate driven by the balance between sympathetic (stress/fight-or-flight) and parasympathetic (rest/recovery) nervous systems. Critically low HRV indicates very impaired autonomic regulation, which is associated with very high cardiovascular mortality risk, very compromised stress resilience, and often reflects serious cardiac, metabolic, or neurological disease.
Seek urgent medical evaluation including cardiac assessment. Very low HRV is a serious health warning that requires comprehensive cardiovascular and neurological evaluation.
HRV (RMSSD) critically low (<10ms) — noticeable autonomic dysfunction; cardiovascular and stress risk elevatedYour HRV is low. Low HRV indicates that your nervous system is in a state of sympathetic (stress/fight-or-flight) dominance with reduced parasympathetic (recovery/rest) activity. This reflects impaired recovery capacity, high allostatic load, and increased cardiovascular risk. Chronic stress, poor sleep, overtraining, metabolic disease, and aging all reduce HRV.
Prioritize recovery: adequate sleep (7–9 hours), stress reduction practices (meditation, yoga, breathing exercises), reduced training load if an athlete, and cardiovascular health optimization. Discuss with your doctor if chronically low.
HRV (RMSSD) low (<20ms) — autonomic imbalance; sympathetic dominance; stress and recovery impairedYour HRV is below the optimal range. Suboptimal HRV indicates reduced autonomic flexibility and recovery capacity. This may reflect lifestyle stress, inadequate sleep, or suboptimal cardiovascular conditioning.
Focus on improving sleep quality, stress management, and aerobic fitness (a consistent aerobic exercise program improves HRV over weeks to months).
HRV (RMSSD) below optimal — reduced autonomic flexibility; recovery capacity compromisedYour HRV is within the normal reference range, indicating adequate autonomic nervous system balance.
No specific action required. Continued aerobic exercise and stress management will maintain or improve HRV.
HRV (RMSSD) within normal range — adequate autonomic balanceYour HRV is in the optimal range. High HRV reflects excellent parasympathetic tone and autonomic flexibility, associated with better cardiovascular health, faster physical recovery, greater stress resilience, and better mental health outcomes.
No action needed. Continue the lifestyle habits (exercise, sleep, stress management) supporting your excellent HRV.
HRV (RMSSD) in optimal range (>50ms) — excellent autonomic balance and recovery capacityYour HRV is above average, reflecting excellent parasympathetic dominance and recovery capacity.
No action needed.
HRV (RMSSD) above average — excellent cardiovascular and recovery fitnessYour HRV is very high, typically seen in elite athletes and individuals with exceptional cardiovascular fitness. This reflects excellent parasympathetic tone.
No action needed. This is an exceptional autonomic health result.
HRV (RMSSD) very high — elite cardiovascular and autonomic fitnessYour HRV is exceptionally high, consistent with elite cardiovascular conditioning. Very high HRV in well-trained athletes is normal and healthy. In non-athletes, rule out measurement artefact or specific cardiac conditions (complete heart block can produce spuriously high HRV).
No action needed if you are a trained athlete. If not an athlete, confirm measurement methodology and discuss with your doctor.
