摘      要：Syncope is precisely defined as a temporary loss of consciousness due to global cerebral hypoperfusion,often accompanied with loss of muscular tension and the failure to maintain active position. Pre-syncope is a state consisting of transient lightheadedness, loss of or weaker muscle tension, but not accompanied with loss of consciousness. Syncope and pre-syncope are common symptoms occurring in children and adolescents. Girls present more morbidity than boys. And patients with syncope accounted for about 1%-2% of all pediatric patients in the emergency department.l＇2 Among medical students at an average age of 20 years, one survey found that about 20% of males and 50% of females reported to have syncope at least once.3 The onset of syncope greatly affects the physical and psychological health of children and adolescents, which is a research hotspot in the field of pediatric cardiology at home and abroad.
