Star·ling curve

(star'ling),
a graph in which cardiac output or stroke volume is plotted against mean atrial or ventricular end-diastolic pressure; with increasing venous return and atrial pressure the output proportionately increases until further increments overload the heart and the output falls.

Frank-Starling curve - Synonym(s): Starling curve
Starling curve - a graph in which cardiac output or stroke volume is plotted against mean atrial or ventricular end-diastolic pressure. Synonym(s): Frank-Starling curve
Starling equilibrium
Starling hypothesis
Starling law of the heart - the energy liberated by the heart when it contracts is a function of the length of its muscle fibers at the end of diastole. Synonym(s): law of the heart
Starling law of the intestine - food causes a band of constriction proximally and relaxation distally, resulting in a peristaltic wave.
Starling reflex - tapping the volar surfaces of the fingers causes flexion.

According to the Frank-Starling curve, two zones can be distinguished: (a) a slope where minimum preload changes give rise to a marked increase in SV (preload dependency zone) and (b) a flat or level segment where the SV hardly varies with changes in preload (preload-independent zone).
In addition, both ventricles must operate on the ascending portion of the Frank-Starling curve (biventricular preload dependence) (9).
