摘　　要：血管迷走性晕厥（vasovagal syncope，VVS）是临床上最常见的不明原因晕厥，其发病机制尚未完全清楚，多认为与触发Bezold—Jarisch反射引起心脏自主神经系统发生矛盾反射导致血管异常扩张、血压下降、心排血量减少、使大脑供血不足而发生晕厥有关。目前认为VVS主要与患者年龄、性别、晕厥病史、晕厥家族史、精神和心理因素、饮食生活习惯等因素有关，但VVS确切的发病因素仍有待多中心、大样本的资料进一步研究。Vasovagal syncope （VVS）is the most common clinical unexplained syncope, and its pathogenesis has not been fully understood yet. The contradictory reflection of cardiac autonomic nervous system caused by riggerring Bezold-Jarisch reflex, which could cause dilated blood vessels, blood pressure and cardiac output decreased, insufficient blood supply to the brain relate with syncope occurrence. Currently, most people consider it mainly relatel to the age and gender of patients, history of syncope, family history, mental and psychological factors, dietary habits and other factors, but the exact risk factors of VVS remains further study of multi-center and a large sample of data.
