WebMyocardial contractility represents the innate ability of the heart muscle (cardiac muscle or myocardium) to contract.The ability to produce changes in force during contraction result from incremental degrees of binding between different types of tissue, that is, between filaments of myosin (thick) and actin (thin) tissue.

WebSystole can be considered the active phase of the cardiac cycle where myocardial contractility becomes the key to left ventricular performance. Left ventricular systolic performance can be graphed on a "Frank-Starling performance curve" which plots left ventricular performance, i.e. cardiac output, as related to left ventricular end-diastolic ...

WebNov 3, 2024 · Frank Starling Curve. The X axis is ventricular end diastolic volume; and the Y axis is stroke volume. As ventricular end diastolic volume increases, stroke volume also increases. The dashed lines indicate where maximal contractility has been exceeded and any filling beyond this point causes a reduction on stroke volume. The Frank–Starling law is named after the two physiologists, Otto Frank and Ernest Henry Starling. However, neither Frank nor Starling was the first to describe the relationship between the end-diastolic volume and the regulation of cardiac output. The first formulation of the law was theorized by the Italian physiologist Dario Maestrini, who on December 13, 1914, started the first of 19 experiments that led him to formulate the "legge del cuore" .
