基于频域分析的脉搏波信号研究

Study of pulse wave based on frequency domain analysis

在人体血液循环系统中,推动血液流动的能源来自心脏的搏动。采用现代测试技术理论,从能量传递的角度,对系统的激励和响应特性进行了理论分析。指出在动脉管壁上测得的压力波信号,作为血液循环系统对心脏搏动激励的响应,含有反映人体健康状况的信息,并进行了实验研究。

In the human blood circulation system,energy promoting blood flow comes from the beating of the heart.In this paper,incentives and response characteristics of the system are analyzed theoretically from the perspective of energy transfer by modern measurement technology.Also pointed out the measured pressure wave signal from the arterial wall,which is the response of the blood circulation system when beating heart is stimulated contains information,which reflects healthy status of the human body.Then we make experimental studies on a sample of seventy-five people＇s pulse waves to extract information based on frequency domain analysis.
