WebIsoproterenol is an extremely potent β 1 - and β 2- agonist that possesses no α-stimulating properties. Therefore isoproterenol increases heart rate, automaticity, and contractility and dilates both venous capacitance and arterial vessels. It may be a good choice for heart-rate maintenance in a denervated nonpaced transplanted heart.
