Answer

Sympathomimetics

Isoproterenol infusion can be used to shorten AV conduction time. Isoproterenol has chronotropic as well as inotropic effects, which result in an increase in cardiac output.

Isoproterenol (Isuprel)

Isoproterenol has beta1- and beta2-adrenergic receptor activity. It binds the beta-receptors of the heart, smooth muscle of bronchi, skeletal muscle, vasculature, and the alimentary tract. It has positive inotropic and chronotropic actions.
