403例小儿24小时脑电图监测分析

对４０３例各类反复发作性症状的患儿进行了２４小时脑电图监测，结果表明：临床确诊癫痫组的阳性率为８２．７％，痫样放电最多出现于非快速眼动睡眠期，限局性放电占６９％。可疑癫痫组中经监测７０％以上排除或基本排除痫性发作。认为２４小时脑电图监测在鉴别临床发作性质，确定癫痫分型，研究癫痫与睡眠的关系，临床发作与脑电图的关系等方面具有较大价值。

24-hour EEG monitoring in children: analysis of 403cases

4-hour EEG monitoring was performed in 403children with repeated seizure of various types. Thepositive rate was 82.7% for defined epilepsy. Epilepticdischarges mainly occurred in NREM stage and focaldischarges accounted for 69%. More than 70% of thechildren suspected of epilepsy were excluded from epi-leptic seizures. 24-hour EEG monitoring is of signifi-cant value in determining seizure characteristics, epi-lepsy types, the relations between epilepsy and sleepand between clinical seizures and EEGs.
