儿童血管迷走性晕厥的临床诊治

摘要

血管迷走性晕厥（vasovagal syncope，VVS）是由自主神经介导、多种因素触发引起周围血管扩张致一过性脑缺血所致的短暂性意识障碍，同时伴有自主肌张力丧失，不能维持站立姿势而晕倒。患儿通常表现为反复发生的晕厥，诱因多为持久站立、体位改变、环境闷热等。目前VVS的治疗主要包括药物和非药物治疗。[临床儿科杂志,2013,31(7)：601-604]%Vasovagal syncope (VVS) was a neurally-mediated functional disease, a transient disturbance of consciousness triggered by transient cerebral ischemia due to peripheral vasodilation resulting from a variety of incentives, accompanied by the loss of muscle tone and even fainting. Children with VVS are characterized by recurrent syncopal attacks induced by prolonged standing, postural changes and muggy environment, etc. Currently treatments of VVS include non-pharmacological therapy and pharmacological therapy.
