Abstract

Acute intravenous administration of reserpine or pretreatment of dogs with Segontin selectively abolished coronary vasodilation and unmasked a constrictor response to stimulation of the cardiac sympathetics. In view of earlier findings of separate coronary vasomotor and cardiostimulatory sympathetic innervation, the results are interpreted to indicate the existence of reserpine resistant short (vasomotor) and reserpine sensitive long (cardiostimulatory) sympathetic postganglionic neurons.
