摘　　要：晕厥是一种常见症状,由外周血管阻力下降和/或心输出量减少导致的短暂脑灌注不足引起。心源性晕厥是最危险的一种晕厥,较其他晕厥死亡率倍增。其中,心律失常是心源性晕厥最常见的原因,无论缓慢性心律失常还是快速性心律失常均可导致晕厥。最新的2018年ESC晕厥指南对晕厥诊治过程进行了修订,着重强调了临床病史、体格检查、立卧位血压测定、12导联心电图和电生理学检查。Syncope is a common symptom caused by transient global cerebral hypoperfusion due to decreased peripheral vascular resistance and/or decreased cardiac output.Cardiogenic syncope is the most dangerous type of syncope,and its mortality rate is double that of other syncopes.Arrhythmias are the most common causes of cardiac syncope.Both bradyarrhythmias and tachyarrhythmias may predispose to syncope.The latest guidelines for syncope have been revised to focus on clinical history,physical examination,standing and supine Bp,12-lead echocardiogram and electrophysiological examination.
