cardiac contractility

Also found in: Dictionary, Thesaurus.

car·di·ac con·trac·til·i·ty

a measure of cardiac pump performance, the degree to which muscle fibers can shorten when activated by a stimulus independent of preload and afterload.


a capacity for becoming short in response to suitable stimulus.

cardiac contractility
the inotropic state of the myocardium; a major determinant of cardiac output and an important factor in cardiac compensation.
