Assessing Ventricular Function
In the intact organism the Ventricular Function Curve is usually presented as the relation between Stroke Volume (or Cardiac Output or stroke work)) and ventricular filling. If we make a graph between filling volume and Cardiac Output, we can derive the Ventricular Function Curve from the pressure-volume relation as follows. If the aortic pressure and thus ventricular pressure in systole is kept constant (Starling experiment), Cardiac Output is proportional to end-diastolic volume (Chap. 13).
