WebThe Frank–Starling Law describes the relationship between LVEDV and CO. According to the Starling Law, CO increases with increasing left ventricular preload until the left ventricle reaches excessive end-diastolic volumes. With excessive end-diastolic volumes, the CO does not change and may actually decrease. WebThe Frank–Starling law of the heart indicates that the increased filling pressure of the right heart results in increased cardiac output. Any increase in output of the right heart is quickly communicated to the left heart as an increased filling pressure. Thus, increased output of the right heart is matched to increased output of the left heart.
