Abstract

An approach to the study of wave processes in the human cardiovascular system is presented in order to identify the constituent components in the complex signal of the pulse pressure wave—direct and reflected waves. This makes it possible to calculate the pulse wave propagation time and velocity, which are indicators that play an established role in the diagnosis and prognosis of cardiovascular diseases. Testing of the approach is based on a combination of methods for measuring the pulse wave with subsequent mathematical processing of empirical data and methods for direct numerical modeling of hemodynamic processes in the arterial tree.

人体心血管系统中中央脉搏波的分解

摘要

为了确定脉压波的复杂信号中的直接波和反射波的组成成分，提出了一种研究人类心血管系统中波过程的方法。这使得可以计算脉搏波传播时间和速度，这是在心血管疾病的诊断和预后中起着确定作用的指标。该方法的测试基于测量脉搏波的方法和随后对经验数据进行数学处理的方法以及对动脉树中血流动力学过程进行直接数值建模的方法的组合。
