cardiac glycoside
any of a group of glycosides characterized by an aglycone consisting of a steroid nucleus with an α,β-unsaturated lactone ring attached at the C-17 position, occurring in certain plants (e.g., Digitalis, Strophanthus, Urginea). Cardiac glycosides increase the force of contraction of cardiac muscle and some are used as cardiotonics and antiarrhythmics.
