Fig 1. Ventriculo-arterial coupling.

Fig 1.

Left Ventricle elastance (Ees) is the slope of the line running from End Systolic Pressure to V0 on the pressure/volume loop (blue line); Arterial elastance (Ea) is the slope of the line running from the Left Ventricle End-Diastolic Volume to the LV End Systolic Pressure (LVESP) on the pressure/volume loop (red line).

Plv: left ventricular pressure; Vlv: left ventricular volume; ESP: end-systolic pressure; SV: stroke volume; SW: stroke work; PE: potential energy; LVef: left ventricle ejection fraction.
