Heart rate variability (HRV) has been proved an efficient measure for evaluating the function of cardiovascular system under the autonomic nerve control. In fact, HRV includes two types of variability: systolic time interval variability (STIV) and diastolic time interval variability (DTIV). Towards a better understanding of STIV and DTIV, this study uses the methods of spectrum analysis with autoregressive (AR) model and sample entropy (SampEn) analysis to compare the differences of STIV, DTIV… CONTINUE READING
