Quantitative Heart Rate Variability Metrics

Quantitative Heart Rate Variability (HRV) metrics are measurements that analyze how much your heart rate fluctuates over time. These variations reflect the balance between your nervous system’s sympathetic (stress) and parasympathetic (relaxation) activity. Higher HRV usually indicates good cardiovascular health and adaptability to stress, while lower HRV can suggest stress, fatigue, or health issues. These metrics help clinicians assess your autonomic nervous system function and overall well-being by examining patterns in the timing between your heartbeats through various statistical and mathematical analyses.
