Multi-scale Order Recurrence Plot based deterministic analysis on Heart Rate Variability in Congestive Heart Failure Assessment

Congestive heart failure (CHF) is a cardiovascular disease associated with the abnormal autonomic nervous system (ANS). Heart rate variability analysis (HRV) main method for quantitative evaluation of function. Common analytical methods HRV include time domain, frequency and nonlinear methods. However, these generally ignore short-term volatility ganglion law. Therefore, this study proposes new parameter to analyze variability-determination multi-scale order recurrence plot (MSORP_DET). This can in patients on multiple scales. analyzed R-R interval 24-hour data from 98 samples (54 normal subjects 44 CHF). The results showed that MSORP_DET could significantly distinguish CHF (p<0.001). Moreover, accuracy screening reached maximum 81.6% by using combination low frequency/high (LF/HF) MSORP_DET, compared 78.6% when LF/HF alone. be used as index screen reveal rhythm ANS more complex than people.
