Figure 1. Schematic explanation of coupling the left ventricular contraction with the systemic arterial tree. In the middle left panels, left ventricular contraction is represented by its end-systolic pressure-volume relationship. Given a particular end diastolic volume (EDV), this relationship can be converted into ventricular end-systolic pressure P s) stroke volume (5Vj relationship, which is shown by the rectilinear curve coursing from the lower left to upper right corner in the graph at the bottom. In the right middle panel, the aortic input impedance property is represented by a rectilinear arterial end-systolic pressure fF, )-stroke volume SV) relationship curve (Eq. (5)). See the text for the explanation of this representation. This arterial Pes-SV relationship is transcribed in the bottom panel in superposition with the ventricular Pe -SV relationship. The intersection of the two Pes-SV relationship curves indicates the end-systolic pressure and stroke volume which should result from coupling a left ventricle with the given EDV and the slope parameter with a systemic arterial tree with the slope parameter...
