Abstract: 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.
