WebA law that states that the stroke volume of the heart increases in response to an increase in the volume of blood filling the heart (the end diastolic volume). The increased volume of blood stretches the ventricular wall, causing cardiac muscle to contract more forcefully (the so-called Frank–Starling mechanisms). The stroke volume may also increase as a result … WebApr 22, 2012 · Starling’s law of the heart. Starling’s law of the heart states that the force of contraction of the heart muscle is directly proportional to the initial fibre length. When the heart muscle fibres are …
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.
