HEART RATE VARIABILITY ANALYSIS AT ARRHYTHMIA WITH SAVED SINUS RHYTHM

The method extending spectral analysis of heart rate variability (HRV) application for patients with sinus arrhythmia was proposed. The method is based on Lyapunovs' central theorem of spectral analysis that bands together total power (TP) and integral from quadratic of function. Рroposed method exactly split mixed model signal on true independent sources; that we obtain stochastic and harmonic sources when we split real HRV records; that TP of harmonic source good correlated with expected TP value for patients' age group. Thus method extends HRV technology for medical practice.
