An unambiguous definition of syncope is important for care, research and teaching purposes. Unfortunately, many published definitions described 'syncope' as a broad category of transient loss of consciousness (TLOC) but still appeared to use a much narrower concept, creating confusion. The ESC-classification from 2001 and subsequently distinguished between 'transient loss of consciousness', i.e. disorders sharing unconsciousness of short duration with a rapid and spontaneous recovery and syncope, the form of TLOC that is due to cerebral hypoperfusion. Adding the cerebral hypoperfusion element sets syncope apart from other forms of TLOC, mostly epileptic seizures and psychogenic attacks. We provide short descriptions of different forms of syncope and other forms of TLOC.
晕厥的明确定义对于医疗、研究和教学目的而言至关重要。遗憾的是，许多已发表的定义将“晕厥”描述为短暂意识丧失（TLOC）的一个宽泛类别，但似乎仍使用了一个更为狭窄的概念，从而造成了混淆。2001年欧洲心脏病学会（ESC）的分类以及随后的分类区分了“短暂意识丧失”，即那些具有短时间意识丧失且能快速自发恢复的疾病，以及晕厥，即由于脑灌注不足导致的TLOC形式。加入脑灌注不足这一要素使晕厥有别于其他形式的TLOC，主要是癫痫发作和精神性发作。我们对不同形式的晕厥及其他形式的TLOC进行简要描述。
