Abstract: Syncope is one of the most common diseases in children. According to the etiology， it can be divided into autonomic nerve mediated syncope， cardiogenic syncope and a small part of unexplained syncope. According to the epidemiology， cardiogenic syncope is the second etiology of syncope in children. In recent years， it has gradually attracted more and more attention from clinicians because of its clinical crisis and severe condition， which requires accurate and active rescue as early as possible， and it is with high rate of sudden death，high risk and poor prognosis. The article comprehensively analyzes the progress of diagnosis and treatment of cardiogenic syncope in children to provide clinicians with a deeper understanding of cardiogenic syncope， so as to improve the survival rate and quality of life after syncope in children.
