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

晕厥必痫发作相鉴别，尽管晕厥发作时也会发生脑氧引起的痫发作。

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.

倾斜试验不推荐用于曾经有低位现场所发生1次晕厥而没有受伤的患者。
