What It Measures
Cardiac Readiness quantifies the autonomic nervous system’s balance and the cardiovascular system’s recovery state through analysis of heart rate patterns from ECG recordings. This system reflects your body’s stress response and recovery capacity.
Key Physiological Indicators
Heart Rate Variability (HRV): Beat-to-beat variation in cardiac intervals
Autonomic Balance: Ratio between sympathetic (stress/“fight or flight”) and parasympathetic (recovery/“rest and digest”) nervous system activity
Stress Index: Cardiovascular strain and adaptation level
Adaptation Reserves: Capacity to respond to life stressors and maintain homeostasis
Rhythm Stability: Detection of arrhythmias or irregular patterns Recovery Efficiency: How well the body has recovered from physical, emotional, and mental stressors
Measurement Source Technology:
Multi-lead ECG recording
Duration: 2-5 minute resting measurement
Position: Supine (lying down) at rest
Analysis Parameters:
Time-domain: SDNN, RMSSD, SDSD
Frequency-domain: VLF, LF, HF power, LF/HF ratio
What Affects Cardiac Readiness?
Decreases with: Physical exertion, insufficient sleep, illness, emotional stress, work pressure, dehydration, alcohol, poor diet
Increases with: Adequate rest, quality sleep (7-9 hours), balanced nutrition, stress management practices, hydration, positive social connections
