摘　　要：本文提出了一种自动检测肺循环血流动力学参数的无创方法 ,并基于 PC和超声心动图仪构建了实用系统。临床试用结果表明 :本系统对肺循环血流动力学参数具有较高的检测精度 ,且使用方便 ,有望在一定程度上代替传统的有创方法——心导管法。A non invasive method is presented to measure the pulmonary circulation hemodynamic parameters automatically. A system with this method is developed based on a personal computer and an echocardiograph. From the clinical application, it is shown that this system has a high measurement precision and is easy to use. It is also predicted that this system can be used instead of the traditional invasive method: the cardiac catheterization.
