目的对儿童发作性疾病的脑电活动进行分析。方法对１５１例发作性疾病儿童应用２４ｈ便携式磁带记录脑电图（ＡＥＥＧ）进行监测。结果总异常率８０８％，痫样放电出现率７９５％。癫痫组痫样放电出现率７８８％，可疑癫痫组痫样放电出现率４５５％，两组之间有非常显著差异（Ｐ＜０００５）。ＡＥＥＧ痫样放电出现率明显高于常规脑电图（ＥＥＧ）；癫痫组与可疑癫痫组之间临床发作中所描记到的痫样放电出现率也有非常显著差异（Ｐ＜００１）。本组病人的痫样放电部位以全脑或一侧，或限局性一侧偏胜者多见，痫样放电时间以睡眠时期为主占７４２％，其中６７７％见于浅睡期。结论２４ｈ动态脑电图监测对于儿童发作性疾病的诊断有着非常重要的意义。
Objective To analyze the EEG activity of seizures in children. Methods 151 cases of children with seizures were monitored by 24-hour portable magnetic recording EEG (AEEG). The total abnormal rate of 80.8%, epileptiform discharge rate 79.5%. Occurrence of epileptic seizures in epileptic group 78.8%, epileptic group suspicious epileptic discharge 45.5%, there was a significant difference between the two groups (P <0005). The incidence of epileptiform discharges in AEEG was significantly higher than that in conventional electroencephalography (EEG). There was also a significant difference in the occurrence of epileptiform discharge observed in clinical seizures between the epileptic group and the suspected epilepsy group (P <001). The group of patients with epileptogenic discharge parts of the whole brain or side, or partial side of the more than the partial winner, epileptiform discharge time to sleep mainly accounted for 74 2%, of which 67 7% seen in shallow sleep . Conclusions 24h dynamic EEG monitoring is very important for the diagnosis of seizures in children.
