Despite the high incidence of pulmonary embolism its diagnosis continues to be difficult, primarily because of the vagaries of symptoms and signs in presentation. Conversely, syncope is a relatively easy clinical symptom to detect, but has varied etiologies that lead to a documented cause in only 58% of syncopal events. Syncope as the presenting symptom of pulmonary embolism has proven to be a difficult clinical correlation to make.
We present the case of a 26-year-old Caucasian man with pulmonary embolism induced-syncope and review the pathophysiology and diagnostic considerations.
Pulmonary embolism should be considered in the differential diagnosis of every syncopal event that presents at an emergency department.
尽管肺栓塞的发病率很高，但其诊断仍然困难，主要是因为其临床表现中的症状和体征变幻莫测。相反，晕厥是一种相对容易察觉的临床症状，但病因多样，仅在58%的晕厥事件中能找到明确病因。晕厥作为肺栓塞的首发症状，已被证明在临床上很难建立关联。
我们报告一例26岁白种男性因肺栓塞诱发晕厥的病例，并回顾其病理生理学及诊断要点。
对于急诊科出现的每一例晕厥事件，鉴别诊断时都应考虑肺栓塞。
