WebDue to increased venous return, the increased stretch leads to an increase in the force of _____ contraction (Frank-Starling Curve) enabling the heart to eject additional blood that was returned to it (EDV increases SV) ... Mitral stenosis are all determinants that will increase / decrease preload. WebFrank-Starling Curves Otto Frank (1899) is credited with the seminal observation that peak ventricular pressure increases as the end-diastolic volume is increased (as in Fig. 8). This observation was made in an isolated frog heart preparation in which ventricular volume could be measured with relative ease.
