摘要
血管迷走性晕厥(vasovagal syncope,VVS)是一种慢性反复发作性疾病,是儿童和青少年晕厥中最多见的病因,约占所有儿童和青少年晕厥的45%~60%。反复晕厥发作严重影响儿童和青少年的学习及其生活质量,引起临床医生的高度重视。VVS的发病机制尚未明确,目前认为主要与自主神经功能障碍相关。因此,检查和评估心脏自主神经功能有助于诊断VVS及预防晕厥发作。该文对心率变异性、QT离散度及P波离散度、心率减速力及连续心率减速力、24 h动态血压监测和运动后心率恢复等自主神经功能检查方法进行综述,探讨其对儿童VVS诊断的有效性。
Vasovagal syncope(VVS)is a chronic recurrent disease.It is the most common cause of syncope in child and adolescents,accounting for 45%~60%of all syncopal cases.Repeated episodes of syncope severely affect the learning of children and adolescents and the quality of life of their families,which has attracted great attention from clinicians.The pathogenesis of VVS has not been clarified,and it is currently thought to be mainly related to autonomic dysfunction.Therefore,examining and evaluating cardiac autonomic function can help to diagnose VVS and prevent syncope.This article reviews the cardiac autonomic tests such as heart rate variability,QT dispersion and P wave dispersion,heart rate deceleration capacity and heart rate deceleration runs,24-hour ambulatory blood pressure monitoring,and post-exercise heart rate recovery to explore its effectiveness in the diagnosis of VVS in children.
