目的对１１０例癫痫患者的２４ｈ动态脑电图（ＡＥＥＧ）的应用价值进行了初步探讨。方法使用英国的ＯｘｆｏｒｄＭｅｄｉｌｏｇ９２００型８导磁带记录仪进行２４ｈ描记后作离线回放分析，并与普通ＥＥＧ相比较。结果１１０例中ＡＥＥＧ异常６２例（５６．４％），９８例中ＥＥＧ发现异常３２例（３２．７％）。ＥＥＧ正常而ＡＥＥＧ异常３０例，ＥＥＧ异常而ＡＥＥＧ正常９例。结论ＡＥＥＧ明显优于ＥＥＧ，但有时ＡＥＥＧ也不能捕获到间歇期的发作波。分析ＡＥＥＧ记录必需注意将睡眠Ⅰ、Ⅱ期出现的高幅顶尖波、纺锤波与痫样波区分开来，以免导致错误诊断。ＡＥＥＧ对颞叶和额叶底面的致痫灶反应较差，需补做特殊电极的ＥＥＧ，如蝶骨电极。
Objective To investigate the value of 24-hour electroencephalogram (AEEG) in 110 patients with epilepsy. METHODS: The data were analyzed offline using an OxfordMedilog 9200 8-tape recorder from the United Kingdom for 24h, and compared with normal EEG. Results Of the 110 cases, 62 cases (56.4%) had abnormal AEEG, and 32 cases (32.7%) showed abnormal EEG in 98 cases. EEG normal and AEEG abnormalities in 30 cases, EEG abnormalities and AEEG normal in 9 cases. Conclusion AEEG is significantly better than EEG, but sometimes AEEG can not capture the intermittent episodes of the wave. Analysis of AEEG records must pay attention to sleeping Ⅰ, Ⅱ high-amplitude top wave, spindle wave and epileptiform wave distinguish, so as not to lead to misdiagnosis. AEEG on the temporal lobe and basal frontal epileptogenic reaction is poor, need to make special electrodes EEG, such as sphenoid electrode.
