安定—脑电地形图敏感试验是研究癫痫的一种新技术。本文报告对４０例正常对照组，１１例假性发作，８例晕厥病人进行安定—脑电地形图敏感试验影响因素研究的结果，发现对照组在静脉注射安定后脑地形图上β功率明显增加，５ｍｉｎ达高峰，持续５ｍｉｎ，随后下降。季节、卡马西平、苯妥英纳对试验无影响，用苯二氮　年类后β功率增加的量则明显减少。假性发作、晕厥病人与对照组无显著区别。 Stability - EEG topographic sensitivity test is a new technology for the study of epilepsy. In this paper, 40 normal control subjects, 11 patients with pseudo-episodes and 8 patients with syncope were studied. The results showed that β-power in the control group was significantly increased after 5-min Peak, lasted 5min, then decreased. The season, carbamazepine, phenytoin did not affect the test, the amount of β-benzodiazepine after the increase was significantly reduced. Pseudo episodes, syncope patients and control group no significant difference.
