Inotropics
Inotropic drugs, such as cardiac glycosides and phosphodiesterase (PDE) inhibitors, increase the force of the heart’s contractions. In other words, the drugs have what’s known as a
positive inotropic effect. (Inotropic means affecting the force or energy of muscular contractions.)

positive inotropic effect. (Inotropic means affecting the force or energy of muscular contractions.)
Cardiac glycosides also slow the heart rate (called a negative chronotropic effect) and slow electrical impulse conduction through the atrioventricular (AV) node (called a negative dromotropic effect).
