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.

WebThe Frank–Starling relationship is a fundamental concept in cardiovascular physiology, relating change in cardiac filling to its output. Historically, this relationship has been … WebThe Frank–Starling law is named after the two physiologists, Otto Frank and Ernest Henry Starling. However, neither Frank nor Starling was the first to describe the relationship between the end-diastolic volume and the regulation of cardiac output.
