Abstract: Pulse wave is one of the important physiological signals in human body. It is an important direction to explore the pulse wave analysis method from the new angle. On the basis of analyzing the existing methods of time domain and frequency domain, the analysis method of complex network was introduced into the analysis of pulse wave to expand the research dimension of pulse wave. Analyzed the present situation of the time series of network method. Horizontal visibility graphs (HVG) network analysis method was used in the analysis of pulse wave network. The characteristic parameters of pulse wave networks were obtained, and the scale-free characteristic of the pulse wave network was determined, which was also be explained in the perspective of physiological state. It provides a new method for the study of pulse wave.

Key words: pulse wave, body area network, complex network, HVG, scale-free
