心脏自主神经系统调节在儿童血管迷走性晕厥中的研究现状

Research status of cardiac autonomic nervous system regulation in vasovagal syncope in children

血管迷走性晕厥(vasovagal syncope,VVS)是自主神经介导性晕厥中最常见的一种类型,其发病机制复杂。自主神经系统包括交感神经和副交感神经,心脏受两者双重支配并保持平衡。目前普遍认为VVS存在心脏自主神经调节功能的失衡。文章就VVS中心脏自主神经主要神经递质的作用、心脏自主神经功能的评价指标及针对自主神经功能失衡的治疗等方面的研究进展作一介绍。

Vasovagal syncope(VVS)is the commonest type of autonomic nerve mediated syncope,and the pathogenesis of VVS is complex.The autonomic nervous system consists of the sympathetic nervous system and the parasympathetic nervous system.The two systems keep the cardiac balance.It is generally accepted that VVS has the imbalance of cardiac autonomic nerve regulation.In this paper,we summarize the research results about the role of cardiac autonomic nerves and their major neurotransmitters,application of cardiac autonomic nerve function tests,and treatment of autonomic nerve dysfunction in VVS.
