目的：分析以晕厥为主诉住院患者的晕厥常见病因，以减少临床误诊和漏诊。方法收集海军总医院近3年以晕厥为主诉的病例145例，根据病史、临床症状和体征以及脑电图、动态心电图、运动试验、超声心动图、立卧位血压等检查结果，分析其病因。结果145例病因构成为神经介导的反射性晕厥(55％)、体位性低血压及直立不耐受综合征(6％)、心源性晕厥(18％)、其他原因性晕厥(21％)，神经介导的反射性晕厥是最常见的原因。心源性晕厥在70岁以上患者中较70岁以下患者显著增多( P<0�05)。结论应提高临床医生对神经介导的反射性晕厥的认识，确诊主要结合临床表现、详细的病史以及辅以直立倾斜试验、动态心电图、运动试验等相关检查。
