| Abstract: | The synchronous pulse signal and electrocardio-graph were processed and the pulse interval and electrocardio-graph interval sequence(PR and RR) were acquired.By using surrogate data method and Lyapunov exponent,the chaotic characteristics of HRV and PRV was determined.The result showed that the notability level of zero-assumption checking of chaotic synchronous pulse signal and electrocardio-graph was greater than 1.96 and Lyapunov exponent was greater than zero.The chaotic characteristics was consistent.Wh... |
