WebApr 3, 2024 · The Frank-Starling relationship is an intrinsic property of myocardium by which increased length (or ventricular volume) results in enhanced performance during the subsequent contraction. 1–3 This … 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.
