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
