目的:观察动态脑电图θ节律在癫中的诊断价值;方法:采用8000型8导AEEG监测仪对100例临床确诊或疑诊为癫的患者及100例正常人进行24hAEEG监测。结果:癫组100例,出现θ节律活动78例(78%),其中一般活动形式18例(18%),阵发性活动44例(44%),暴发性活动16例(16%)。在θ节律活动基础上伴有样放电的48例(61.5%)。对照组100例,出现θ节律活动16例(16%),一般活动形式13例(13%),阵发性活动3例(3%),未见暴发性活动与样放电。结论:AEEG监测出现一般活动形式的θ节律,一般是非特异性的,对癫的诊断无临床意义;而出现阵发性或暴发性θ节律活动对癫的诊断有很高的价值。
OBJECTIVE: To observe the diagnostic value of dynamic EEG θ rhythm in epilepsy.METHODS: Eighty-four 8-lead AEEG monitors were used to monitor 24hAEEG in 100 clinically diagnosed or suspected epileptic patients and 100 normal subjects. Results: In the epilepsy group, 78 cases (78%) showed rhythmic activity of the rhythms, 18 cases (18%) were general activities, 44 cases (44%) were paroxysmal activities and 16 cases (16% . 48 cases (61.5%) accompanied by discharge on the basis of θ rhythm. In control group, there were 16 cases (16%) of rhythmic θ events, 13 cases of general activity (13%) and 3 cases of paroxysmal activity (3%). No outbreaks and discharges were observed. CONCLUSIONS: The AE rhythms of general active forms monitored by AEEG are generally nonspecific and have no clinical significance for the diagnosis of epilepsy. However, the occurrence of paroxysmal or fulminant θ rhythmic events is of great value in the diagnosis of epilepsy.
