近二十年来,人们为了研究心脏的泵功能及其机械性质,做了大量的工作。但由于生物体高度的复杂性和非线性,人们对于这些性质的研究至今仍处于探索之中。由于心脏的泵功能主要是指左室的收缩功能,因而在这里仅仅讨论左室的机械性质、各种研究方法及描述左室功能的数学模型和物理模 For nearly two decades, people have done a great deal of work to study the heart’s pump function and its mechanical properties. However, because of the complexity and non-linearity of organisms, the research on these properties is still under exploration. Since the cardiac pump function primarily refers to the left ventricular systolic function, it is here to discuss only the mechanical properties of the left ventricle, various research methods, and mathematical and physical models that describe left ventricular function
