Frank starling curve images

The 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. The first formulation of the law was theorized by the Italian physiologist Dario Maestrini, who on December 13, 1914, started the first of 19 experiments that led him to formulate the "legge del cuore" . WebJan 7, 2024 · Changes in venous return cause the ventricle to move along a single Frank-Starling curve that is defined by the existing conditions of afterload and inotropy and diastolic compliance; stroke volume is not governed by venous return (the flow of blood) and is not controlled by the ventricles or Starling’s Law, but by atrial stretch ...

WebEditor-In-Chief: C. Michael Gibson, M.S., M.D. Overview. The Frank-Starling law of the heart (also known as Starling's law or the Frank-Starling mechanism) states that the more the ventricle is filled with blood during diastole (end-diastolic volume), the greater the volume of ejected blood will be during the resulting systolic contraction (stroke volume).
