inotropic

Influencing the force or speed of muscular contractility. Inotropic agents, such as dobutamine and dopamine are used to improve the output of the heart in the treatment of HEART FAILURE and sometimes in acute circulatory failure (SHOCK).

inotropic

affecting or controlling the strength of heart contractions. For example, chemicals that increase the force of contraction have a positive inotropic effect.
