WebOct 11, 2024 · The Frank-Starling mechanism is a fundamental regulatory property which underlies the cardiac output adaptation to venous filling. Length-dependent activation is generally assumed to be the cellular origin of this mechanism. At the heart scale, it is commonly admitted that an increase in preload (ventricular filling) leads to an increased ... WebMarc E. Stone MD, in Essentials of Cardiac Anesthesia for Noncardiac Surgery, 2024 Frank-Starling Mechanism. The Frank-Starling law holds that increased stretch on the myocytes (to a point) increases the force of their contraction.As the ventricle fills, the potential force of the myocardial contraction increases because stretching of the muscle …
