It is a common emergency in pediatric clinics. About 15% of children and adolescents have had at least once syncope before IS years old, and syncope accounts for 1 % of all pediatric emergencies.

Based on the recent developments in related fields in recent years, this review introduces the epidemiological characteristics, pathogenesis, diagnostic procedures and future research directions of Children's neuro-mediated syncope, with a view to improving clinicians understanding of Children's neuro-mediated syncope and further improving diagnosis and treatment of syncope in China.
