Webb23 aug. 2024 · Ernest Starling in 1914 formulated the Law of the Heart to describe the mechanical property of cardiac muscle whereby force of contraction increases with muscle length. He subsequently, in 1927, showed that the oxygen consumption of the heart is also a function of the length of the muscle fibre, but left the field unclear as to whether … WebbIn 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.
