目的了解动态脑电图(AEEG)中睡眠中放电与过度换气脑电图(EEG)的放电规律.方法评估65例额叶癫痫患者AEEG与过度换气EEG的痫性放电特点.结果过度换气中发现痫性放电率明显低于AEEG中浅睡眠期(非快速眼动相1,2期)EEG,差异具有统计学意义(P＜0.05);而与AEEG中清醒期和深睡眠期(非快速眼动相3,4期)比较,差异无统计学意义(P＞0.05).结论额叶癫痫患者AEEG中浅睡眠期痫性放电率明显高于过度换气EEG,对额叶癫痫患者进行睡眠AEEG检测,有助于提高痫性放电的诊断率.

Objective To study the discharges regularity of ambulatory electroencephalogram (ambulatory,EEG,AEEG)during sleep and hyperventilation(HV)-induced EEG. Methods Features of epileptiform discharges of AEEG and HV-induced EEG were evaluated comparatively in 65 cases with frontal lobe epilepsy. Results The epileptiform discharge rate of HV-induced EEG was evidently lower than that of AEEG during the shallow sleep period (non-rapid-eye-movement phase 1 and 2,NREM phase 1 and 2),which had statistical significance(P＜0.01);however,the rate of HV-induced EEG had no significant difference from that of AEEG during the awake period and deep sleep period(NREM phase 3 and 4)(P＞0.05). Conclusions The epileptiform discharge rate of AEEG during the shallow sleep period is obviously higher than that of HV-induced EEG in patients with frontal lobe epilepsy,and thus sleep EEG is helpful to enhance the diagnostic rate of epileptiform discharges in these patients.
