摘　　要：晕厥是由短暂的全脑组织缺血导致的短暂意识丧失,其特点为发生迅速的、短暂的、自限性的,并且能够完全恢复意识。晕厥在人群中尤其是老年人中有十分高的发生率。心源性疾病可以作为一个独立的判断远期发生严重事件的危险因素。神经源性晕厥因其缺乏心源性疾病为基础,预后相对较好。晕厥的发作频率是十分重要的判断晕厥反复发作的危险因素。晕厥导致的创伤,因神经源性晕厥常伴有一个较明显的前驱症状而相对较低,心源性晕厥则由于缺乏明显的前驱症状,发生创伤的概率较大。正确地分析晕厥的危险因素,可以指导临床医师做出更加个体化的随访方式,以期改善患者的预后。Syncope is a transient loss of consciousness due to transient global cerebral hypoperfusion characterized by rapid onset,short duration,and spontaneous complete recovery.The incidence of syncope is quite high in the general population,especially in the elderly population.Organic heart disease can be considered a risk factor in evaluating the severe outcome of patients with syncope.In the absence of organic heart disease the severity of the outcome for patients with neurogenic syncope is significantly lessened.Also,the trauma caused by syncope is much less in patients with neurogenic syncope with a longer duration of prodrome.A proper risk stratification of syncope can help the clinician make a better follow-up plan for patients with different kinds of syncope.
