【摘要】 本文报告了３１３例经ＣＴ证实为脑梗塞的脑电图，异常率为９０．４％。并分组着重对中度和重度脑电图异常率和定位准确率进行分析比较，发现各组间存在着显著差异（Ｐ＜０．０１）。病变靠近脑表面者脑电图异常表现较明显。病变范围越大，病灶越多，脑电图改变越明显，定位准确率也较高，而临床预后则较差；相反，单发性腔隙性脑梗塞由于梗塞部位深，病灶小，脑电图改变不明显，预后则较好。更多还原

【Abstract】 Abstract Affiliated Hospital of Guangzhou Medical College.Guang zhou(510120))Abstract:The abnormality rate of EEG of 313 patients with cerebral infarction confirmed by CT was 90. 4%.The patients were grouped according to the degree and localization of the infarction.The authors found that the abnormality of EEG among the groups showed a significant difference (P<0.01).In patients with infarction adjacent to cerebral surface, the prognosis was poor when the range of the lesion was great,the focus was multiple,the EEG change was remarkable and the localization was accurate,On the contrary, in patients with single lacunar infarction,the prognosis was good when the lesion was deep,the focus was small,and the EEG change was not remarkable.更多还原
