75例颞叶癫癎患者动态EEG与过度换气EEG癎样放电规律探讨

目的：了解睡眠EEG与过度换气EEG的痢样放电规律。方法：评估75例颞叶癫痫患者动态EEG与过度换气EEG的痫样放电特点。结果：过度换气EEG痫样放电检出率明显低于浅睡期EEG，差异具有极显著意义（P〈0．01）；但与清醒期和深睡期EEG痫样放电检出率比较差异无显著意义（P〉0．05）。结论：颞叶癫痫患者浅睡期EEG痫样放电率明显高于过度换气EEG，对颞叶癫痫患者进行睡眠EEG检测，有助于提高痫样放电的检出率。

Study on epileptiform discharges regularity of ambulatory EEG and hyperventilation EEG in 75 patients with temporal lobe epilepsy

Objective:To evaluate the relation of hyperventilation(HV)-EEG and ambulatory EEG of different stages on the sensitivity of the interictal EEG in temporal lobe epilepsy(TLE).Methods:HV-EEG and ambulatory EEG were examined in 75 patients with temporal lobe epilepsy.Results: During stage of light-sleep,epileptiform discharges(ED) were more frequent than during/after HV-EEG(P<0.01).Compared with the waking EEG and all deep-sleep stages EEG,light-sleep stage EEG was associated with the strongest epileptic activation.There was no difference between the HV-EEG,waking state EEG and deep-sleep stages EEG.Conclusions: In patients with TLE,light sleep stage EEG shows a significantly higher sensitivity for epileptiform discharges than 3 min of HV-EEG in patients with the clinical diagnosis of TLE.Measures to record light sleep stage EEG can help raise the decision rate of epileptiform discharges.
