1、热性惊厥患儿脑电图异常波形及形成特点研究(附280例报告)(湖南郴州市第一人民医院儿童医院湖南郴州423000)��【摘要】目的;探讨热性惊厥患儿波形和部位分布的特点。方法通过对280例临床诊断为热性惊厥的患儿采用视频睡眠剥夺脑电图2h进行回顾性分析,观察其波形和部位分布的特点。结果206例单纯性热惊厥患儿异常VEEG178例(86.4%),正常28例(13.6%),出现不典型尖波散发或成簇发放92例(44.7%),有尖(棘)慢波棘波痫样放电伴有或不伴有背景活动减慢51例(24.8%),12例(5.8%)仅有背景活动变慢;其他如纺锤波缺如、局灶性异常,
2、阵发性节律性快波异常等23例(11.7%);72例复杂性热性热惊厥患儿中,34例(47.2%)9出现痫样放电,伴有或不伴有背景活动减慢;出现不典型尖波16例(22.2%),仅有背景活动减慢7例(9.7%),其他8例(11.1%),7例为正常脑电图,占9.7%。其痫样放电或出现不典型尖波的部位常见于额区和(旁)中央区,其次是中央颞区,再次是顶区和枕区。结论热性惊厥患儿脑波异常以不典型或不规则尖波方式出现最多,常常为额区及(旁)中央区,与患儿的发育不成熟、脑功能不稳定关系密切,以及与额区具有较多功能和解剖区域,存在不同的放电传播途径有关。�【关键词】热性惊
