Syncope is a relatively common clinical syndrome that is a subset of a broader range of conditions that cause transient loss of consciousness (TLOC). Other TLOC conditions include seizures, concussions, and intoxications. However, despite frequent confusion in the medical literature, syncope is and should be clearly distinguished from those other causes of TLOC by virtue of its pathophysiology; specifically, syncope is the result of self-terminating inadequacy of global cerebral nutrient perfusion, while the other forms of TLOC have different etiologies. Unfortunately, the diagnostic evaluation of syncope remains for the most part poorly managed and inefficient. Careful history-taking, physical examination, and judicious use of tests can not only increase the diagnostic yield of the evaluation, but also increase patient safety and reduced overall healthcare costs.
晕厥是一种相对常见的临床综合征，是导致短暂意识丧失（TLOC）的一系列更广泛病症的一个子集。其他TLOC病症包括癫痫发作、脑震荡和中毒。然而，尽管医学文献中常常存在混淆，但晕厥因其病理生理学原因，过去是、现在也应该与其他TLOC病因明确区分开来；具体而言，晕厥是全脑营养灌注自我终止不足的结果，而其他形式的TLOC有不同的病因。不幸的是，晕厥的诊断评估在很大程度上仍然管理不善且效率低下。仔细的病史采集、体格检查以及明智地使用检查方法，不仅可以提高评估的诊断率，还可以提高患者安全性并降低总体医疗成本。
