Role of the adrenergic nerve terminal in digitalis-induced cardiac toxicity: a study of the effects of pharmacological and surgical denervation.

Abstract

This study determined whether the protective action of bretylium against ouabain-induced ventricular arrhythmia in the cat is related to an action of bretylium on the adrenergic nerve terminal. Bretylium pretreatment (20 mg/kg, i.v.) administered 2 h prior to ouabain (2 micrograms/kg/min, i.v. until death) increased the dose of ouabain to produce premature… (More)
