左心室（LV）泵功能的数值模型，结合心肌力学和LV几何形状，用于推导一个简单的线性模型的局部LV收缩性能。该简化模型将心室视为与两个时变元素耦合的压力发生器（与等容收缩相关）：1）粘性项（与心肌的耗散性质相关），和2）弹性项（与激活纤维的张力-长度曲线和LV几何形状相关）。
A numerical model of left ventricular (LV) pump function, incorporating cardiac muscle mechanics and LV geometry, was used to derive a simple linear model of local LV contractile properties. This simplified model views the ventricle as a pressure generator (related to isovolumic contraction) coupled with two time-varying elements: 1) a viscous term (related to the dissipative properties of the myocardium), and 2) an elastic term (related to the tension-length curve of activated fiber and to LV geometry).
