Abstract

Effect of vagal stimulation on the shortening or suppression of ventricular
fibrillation (VF) induced by single extrasystolic stimulation in acute ischemic
myocardium in rabbits was observed. This shortening effect of vagal stimulation
on the VF was not affected by simultaneous administration of #beta#-adrenergic receptor blocker propranolol. This experiment suggests that enhancement of vagal tone may play a beneficial effect in the termination of VF.

Key words: Acute myocardiac ischemia;Ventricular fibrillation;Vagal stimulation;#beta#-adrenergic blockade
