Presets:
Physiological Insight: Heart rate variability measures beat-to-beat timing changes, not average speed. Higher variability (larger RMSSD) reflects healthy vagal nerve modulation dynamically adjusting heart rate to respiration.
Poincaré Plot (RRn vs RRn+1)
SD1: 38ms | SD2: 95ms
The ellipse width (SD1) directly quantifies short-term beat-to-beat variability and vagal tone flexibility.
Interactive Pulse & Bio-Acoustics
Enable acoustic pulse to hear the distinction between rigid, metronomic stress beats vs. rich, flexible autonomic arrhythmia.
