What is the classification of cardiac glycosides?
According to the type of unsaturated lactone ring attached to the C17 position of the cardiac glycoside, the cardiac glycoside can be classified into two types: type A (a five-membered unsaturated lactone ring) and a type B (a six-membered unsaturated lactone ring).

Cardiotonics increase cardiac output through positive inotropic activity (an increase in the force of the contraction). They slow the conduction velocity through the atrioventricular (AV) node in the heart and decrease the heart rate through a negative chronotropic effect.
