WebIn normal heart muscle, the response of the contractile filaments to calcium ions depends strongly on sarcomere length thus explaining Starling's Law of the heart. Recent evidence suggests that this sensitivity is largely lost in congestive heart failure thereby reducing the effectiveness of stretch of cardiac cells on the mechanical output.

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). WebThe Frank–Starling law of the heart (also known as Starling's law and the Frank–Starling mechanism) represents the relationship between stroke volume and end diastolic volume. The law states that the stroke volume of the heart increases in response to an increase in the volume of blood in the ventricles, before contraction (the end diastolic volume), when …
