摘　　要：晕厥患者在神经科、心血管内科较常见,患者会很惊恐,医生会尽力查找病因,其中血管迷走性晕厥最常见,心源性晕厥最凶险,弄清楚病因以便预防猝死非常重要,但是仍有一半以上的晕厥病例查找不到病因。本文从一个个晕厥的病例入手,介绍了主动脉夹层、缓慢性心律失常、肥厚型心肌病、主动脉瓣狭窄、冠状动脉病变、肺动脉高压、肺动脉栓塞、上消化道出血、胆心综合征、脑心综合征以及埋藏式心脏复律除颤器(ICD)术后患者发生晕厥的临床特点,并试图分析晕厥发生的可能机制,为临床医生提供借鉴。Syncope patients admitted in the Department of Neurology, and Cardiology are not rare. The patient will be very frightened, the doctor will try to find the cause, among which vasovagal syncope is the most common and cardiogenic syncope is the most dangerous. Establishing the etiology to prevent sudden death is very important, but there are still more than half of the syncope patients who can not be found the cause. In this article, we introduce the syncope cases of aortic dissection, brady arrhythmia, hypertrophic cardiorayopathy, aortic valve stenosis, coronary artery disease, pulmonary hypertension, pulmonary embolism, upper digestive tract bleeding, biliary cardiac syndrome, cerebral heart syndrome and post-ICD （implantable cardioverter defibrillator）, and try to analyze the possible mechanism of each syncope case.
