Abstract:
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.
