Nonlinear Dynamic Analysis of Wrist Pulse with Lyapunov Ezponents
The cardiovascular system is complex system containing many nonlinearities. Pulse signals reflect the status of the heart and the vascular system. The chaotic properties of wrist pulse were seldom studied. Lyapunov exponents analysis can estimate the chaotic properties of the system. In this paper the wrist pulse signals of healthy group and coronary heart disease group are analyzed and studied with Lyapunov exponents analysis, and the selection of parameters is discussed. The results indicated that there was difference between two groups of wrist pulse signals, and nonlinear dynamic methods of wrist pulse analysis were helpful for non-destructive inspection of coronary heart disease.
