Abstract
A mathematical model is described which in a simplified way, without directly taking into account the elastic properties of the heart wall, describes the EDV which corresponds to the experimental data. The model further describes the power generation of the left ventricle at high EDV. The volume density of power is expressed with a product of three factors (1) average density of the CE, (2) a factor which contains the inotropic properties of a single CE and (3) a form factor, which involves structural changes in the heart wall at various EDV.
摘要
描述了一种数学模型，该模型以简化方式，在未直接考虑心脏壁弹性特性的情况下，描述了与实验数据相对应的舒张末期容积（EDV）。该模型还描述了高EDV时左心室的能量产生。能量的体积密度由三个因素的乘积表示：（1）收缩元件（CE）的平均密度；（2）包含单个CE变力特性的一个因素；（3）一个形状因子，它涉及不同EDV时心脏壁的结构变化。
