Department of Mechanics and Ensineering Science, Peking University, Beijing 100871, P. R. China

摘要

摘要: 本文首次在心脏和血管动态耦合的基础上,研究了人体体动脉中压力和流量脉搏波的传播.左心室采作E(t)-R模型,体动脉树用T-Y模型,应用传输线理论和傅氏分析,选取了合适的心血管参数,得到了沿体动脉各处压力和流量的波形,并研究了心血管各参数对脉搏波传播的影响,对于实际工作很有帮助.

Abstract: For the first time.the pressure and flow pulse wave propagation phenomenon isstudied in this paper on the basis of the cardiovascular dynamic coupling.E(t)-R modelis adopted for left ventricle and T-Y tube model for systemic arteries.Furthermore,impulse response method and Fourier analysis method are employed.After reasonablecardiovascular parameters and their value have been selected,the pressure and flowwaveforms are obtained at any poing along the systemic arteries.The results fitmeasured data well.In addition,the influences of cardiovascular parameters on pulsewave propagation are studied.The work is useful in practice.
