头皮或侵入电极记录癫痫发作的技术正不断发展。作者发现一种奇特的有规律的顿挫性发作,称之为“开始—停止—再开始”(Start-stop-start,SSS),现象。并研究了此现象的脑电波形、发作间期、部位、发生率及与无SSS现象的其它发作的关系。 为探讨SSS现象对98例临床反复发作进行了硬膜下描记。要求具有以下特征:(1)开始期:连续的发作波并伴有持续最少一秒的临床或亚临床发作,这种电波为节律性波,连续棘波和/或棘慢波。(2)停止期:在开始的早期各导完全或几乎完全停止放电1～10秒。停止期又分为(a)完全恢复到发作前的脑波,(b)有明显的恢复但仍伴有连续的发作波,(c)类似发作后的波形,δ和/或波衰减。(3)再开始期:具有临床发作表现并记录到连续的发作波。环状不锈钢电极经钻孔在左右颞、额叶眶部插入,每
Scalp or invasive electrodes recording seizures are evolving technologies. The authors found a peculiar, regularly occurring frustrated episode called the “Start-stop-start” (SSS) phenomenon. The relationship between EEG waveform, seizure interval, location, incidence and other seizures without SSS was also studied. In order to explore the SSS phenomenon of 98 cases of clinical recurrent subdural tracing. Requires the following characteristics: (1) the beginning of: continuous seizures accompanied by a minimum of one second sustained clinical or subclinical seizures, such waves rhythmic waves, continuous spikes and / or spikes and waves. (2) Stall Period: In the early days of the beginning, all the guides stop discharging completely or almost completely for 1 to 10 seconds. The stop period is further divided into (a) a complete recovery of the brain wave before the onset, (b) a significant recovery but with continuous episodes of wave, and (c) similar post-onset waveforms, δ and / or wave attenuation. (3) The resurgence period: with clinical seizure performance and record the continuous seizure wave. Ring-shaped stainless steel electrodes were drilled in the left and right temporal, frontal orbital parts inserted, each
