Myocardial contractility - Wikipedia
A measurable relative increase in contractility is a property of the myocardium similar to the term "inotropy". Contractility may be iatrogenically altered by the administration of inotropic agents.
Cardiac contractility: Video, Causes, & Meaning | Osmosis
Contractility is the ability of the heart muscle to contract and thereby pump blood. Cardiac contractility is determined by the interaction between intracellular calcium concentration, and …
