脑电地形图选段编辑对阵发癲癇波的定位作用

目的探讨脑电地形图(BEAM)选段编辑功能对阵发性棘波、尖波、棘(尖)慢综合波(称癲样放电波)的定位作用.方法将42例癫癇患儿脑电图(EEG)记录到的阵发性癇样放电波进行BEAM定量分析,以棘(尖)慢综合波的慢波高功率定位.结果 EEG癲样放电波定位于双侧额区14%、单侧颞中央区45%、颞区24%、中央区17%.BEAM选段编辑,癲样放电波定位于单侧额区14%、颞区50%、中央区36%.结论 BEAM选段编辑局部定位灵敏度比EEG高60%(P《0.01),是对癇样放电波有一定定位作用的监测手段.

Localization role of BEAM selective editor for paroxysmal epileptiform discharges

Objective To investigate the location role of dynamic BEAM selector editor for paroxysmal sharp wave, spike wave and sparp and slow wave complexes (epileptiform discharges ) . Methods The EEG of 42 children with epilepsy were quantitatively analyzed for paroxysmal epileptiform dischorges with BEAM, and the high energy slow wave in the sharp and slow waves was as its location evidence . Results The EEG epileptoid wave located to both sides of frontalis 14%, central temples 45%, temples 24% and central 17% with the BEAM average calculation. Epiileptoid wave located to frontalis 14% , temples 50% and central 36% with the BEAM selective editor. The sensitivity of the EEG was 60% higher than the BEAM average calculation for the location of paroxysmal epileptoid wave ( P < 0.01) . Conclusion The BEAM selective editor is a useful way to locate epilepsy wave.
