儿童血管抑制型血管迷走性晕厥诊断研究进展

Advances in the diagnosis of vasoinhibitory vasovagal syncope in children

儿童血管抑制型血管迷走性晕厥(vasoinhibitory vasovagal syncope,VVS-VI)是血管迷走性晕厥(vasovagal syncope,VVS)中的最常见反应类型,发病率较高。VVS-VI是自主神经系统功能反应不良而引发的一种反复发作性疾病,可由强烈的情绪、突然改变姿势、闷热环境和长久站立等多种刺激引起。研究发现,VVS-VI是良性疾病,非器质性病变,具有自限性、可逆性的特点,但是患儿常因二次损伤导致不可逆的后果。VVS-VI严重影响患儿的生活与学习,危害患儿的身心健康,引起家长的焦虑。因此,近年来VVS-VI相关研究不断增多。该文对儿童VVS-VI诊断研究进展进行综述,为相关研究提供参考。

Vasoinhibitory vasovagal syncope(VVS-VI)in children is the most common type of responses in vasovagal syncope(VVS)and has a high incidence.VVS-VI is a recurrent disorder caused by a malfunctioning autonomic nervous system.VVS-VI can be caused by a variety of stimuli such as strong emotions,sudden changes in posture,hot and stuffy environments and prolonged standing.It was found that VVS-VI is a benign disease without organic lesions and is self-limiting and reversible,but VVS-VI children often suffer irreversible consequences due to secondary injuries.VVS-VI seriously affects the life and academic performance of children,endangers their physical and mental health,and causes anxiety among parents,so the number of studies on VVS-VI has increased in recent years.This article summarizes the progress of diagnostic research on VVS-VI in children,and provides a reference for related research.
