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。
A single pre-stimulation of ventricular fibrillation that causes termination of acute ischemic heart. Electrical stimulation of the left cervical vagus nerve peripheral end can shorten the duration of ventricular fibrillation. Intravenous β-blocker propranolol, to stimulate the vagus nerve disappears on ventricular fibrillation. Experiments show that increased vagal tone may play a beneficial role in termination of ventricular fibrillation.
