摘要

单个期前刺激引起急性缺血心脏能终止的心室纤颤。电刺激左侧颈迷走神经外周端可以缩短心室纤颤的持续时间。静脉注射β受体阻滞剂心得安后,刺激迷走神经对心室纤颤的作用消失。实验表示增加迷走神经的紧张性可能对终止室颤起有益作用。

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
