用恒定的射血间期对兔子左心室所做的实验表明左心室压力可以用一个随时间变化的包括倒电容E_e(t)、电阻R(t)和串联倒电容Es(t)的三要素模型来描述。以前的实验证明了在一个恒定的射血间期终止后存在一个可以用倒电容Ee(t)的减小来描述的“去激活作用”。本文给出一个基于恒定射血实验结果并用于测量压力和容积数据的模拟模型。结果表明当将此模型 Experiments on a rabbit left ventricle using a constant ejection interval show that left ventricular pressure can be measured by a three-factor element of time-dependent changeover including the capacitor E_e (t), the resistor R (t), and the series capacitor Es Model to describe. Previous experiments demonstrated that there is a “deactivation” that can be described by the decrease of the inverted capacitor Ee (t) after a constant ejection interval expires. This paper presents a simulation model based on constant ejection results and used to measure pressure and volume data. The results show that when this model is used
