Ventriculo-arterial coupling is expressed as the ratio Emax/eam (maximum ventricular elastance/arterial elastance). Different areas under the end-systolic pressure-volume relation (ESPVR) are expressed in terms of Emax/eam. The explicit inclusion of the active force of the myocardium in the mathematical formalism describing the pressure-volume relation (PVR) leads to new insight into the mechanics of left ventricular contraction. Applications to experimental data related to stroke work area SW under ESPVR are discussed and provide further evidence for the consistency of the mathematical formalism used.
心室-动脉耦合表示为Emax/eam（最大心室弹性/动脉弹性）的比值。收缩末期压力-容积关系（ESPVR）下的不同面积以Emax/eam表示。在描述压力-容积关系（PVR）的数学形式中明确纳入心肌的主动力，可对左心室收缩力学产生新的认识。讨论了该数学形式在ESPVR下与搏功面积SW相关的实验数据中的应用，并为所用数学形式的一致性提供了进一步证据。
