    Abstract:
    Quinidine syncope is an unpredictable side effect of quinidine administrateion which has a mortality rate of 11.5 per cent when managed with conventional drugs and direct-current countershock. In 2 patients with quindine syncope, the arrhythmias were effectively controlled within 30 minutes following the slow infusion of 150 mg. of bretylium tosylate. This control is contrasted with 2 cases managed in the conventional manner. Bretylium tosylate is a quaternary amine with unique antifibrillatory properties and appears to have a significant role in the management of these arrhylmias.
