摘要
血管迷走性晕厥(VVS)是临床中的最常见晕厥原因,是指各种刺激通过迷走神经介导反射导致血管扩张及心率减慢,造成脑部低灌注缺氧而出现短暂的意识丧失。VVS发作前有情绪紧张、长时站立等诱因并伴有典型的前驱症状。VVS是一种预后相对良好的疾病,在健康宣教的基础上,一般不需要特殊治疗,发作频繁、症状重者可考虑药物、起搏器或神经消融治疗。
Vasovagal syncope （ VVS ） is the most common type of syncope. It refers to syncope caused by vasodepressor and cardioinhibition,which were mediated by many kinds of vagal reflexes. Typical VVS episodes are preceded by warning prodromes with obvious induce- ments. VVS is a benign disease,generally needn＇t special treatment but lifestyle instruction. The patients with frequent episodes of VVS maybe need special therapy, such as drugs or pacemaker or selective vagal denervation.
