摘要
应用多数模型的分析方法对脉搏压力信号的生理特征进行了研究，从脉搏压力信号参数模型的极点分布中判断心血管系统的不同生理状态，揭示了脉搏压力信号所包含的心血管系统状态信息，从而对心血管功能的分类与评定进行了探索。
In order to study the characteriastics of pulse pressure signal,a parametric modeling method which can be used to describe quantitatively the circulation system is put forward in this paper.Through analysing the change of the pole-point distribution of the parametric Modeling,the different states of cardiovascular function can be identified.The clinical diagnoses show that the identification of cardiovascular fuction through analying the patients pulse pressure signal is of great help in the evaluation of cardiovascular function.
