Syncope must be differentiated from epileptic seizures, although seizures due to brain hypoxia can occur in a syncopal episode.

晕厥必须与癫相鉴别，尽管在晕厥时也会生脑氧引起的癫。

Head up tilt table testing is not warranted in patients who hae experienced a single syncopal episode without injury in an intermediate or low risk setting.

倾斜试验不推荐用有过在低位现场所生过1次晕厥而没有受伤的患者。
