对１３３例癫痫患者的脑电地形图（ＢＥＡＭ）进行了分析，并对ＢＥＡＭ在癫痫诊断中的若干方法学问题进行了探讨。表明ＢＥＡＭ对继发性全身性发作和部分性发作显示较高的异常检测率和定位率。病变部位δ、θ频率能量值增高、α频率显示低能量功率值。原发性癫痫发作间歇期，棘、尖波发放能量与背景脑电活动相比，能量较弱，使计算机对棘波的分析处理较为困难，故５例常规脑电图显示棘、尖波发放，而ＢＥＡＭ未能显示棘、尖波地形图。异常率的检测和病灶部定位与临床操作技术有相互关系。
EEG topographic maps (BEAM) were analyzed in 133 epileptic patients and some of the methodological issues of BEAM in the diagnosis of epilepsy were explored. BEAM showed secondary to systemic and partial seizures showed a higher rate of abnormal detection and positioning rate. Lesions site δ, θ frequency energy value increases, α frequency shows low-power power value. Primary intermittent epileptic seizures, spine, spike release of energy compared with the background of brain electrical activity, the energy is weak, the computer spike analysis and treatment more difficult, so 5 cases of conventional EEG shows spine, spike release , BEAM failed to display spine, sharp wave topographic map. Abnormal rate of detection and lesion localization and clinical operation of technology has a relationship.
