方法收集104例出生~ 18岁患者的脑电图资料。受试者代表了一系列连续的儿科患者，他们被诊断为癫痫发作或疑似癫痫发作。睡眠剥夺后，使用标准技术（美国脑电图学会，1994年）在TECA DG32数字脑电图机（TECA公司，Pleasantville， NY.）上记录所有脑电图。采样率为240/s，分辨率为12位。所有研究均采用10-20国际电极放置系统。在参考蒙太奇和双极蒙太奇上记录18个通道的脑电图，长度至少为30分钟。所有年龄足够配合的患者都进行了过度通气，所有患者都进行了光刺激。脑电图技术专家使用四种预先确定的参照蒙太奇和双极蒙太奇，就像记录在纸上一样进行研究。技术人员在录制过程中根据需要更改了过滤器设置和灵敏度。所有的研究都存储在光盘上。此外，其中一部分（n= 57）也被印在纸上。这张纸的高度为21.5厘米，通常至少显示16个通道。一秒钟包含30毫米。所有数字解译使用的DG32脑电图机视频屏幕宽23厘米，高18厘米（含迹区）。一秒钟就有23毫米。
METHODSThe EEGs of 104 patients, ages birth to 18 years, were included. The subjects represented a consecutive series of pediatric patients referred for evaluation with the diagnosis of seizure or suspected seizure. All EEGs were recorded on a TECA DG32 digital EEG machine (Teca Corporation, Pleasantville, NY.) after sleep deprivation using standard techniques (American Electroencephalographic Society, 1994). The sample rate was 240/s with 12-bit resolution. All studies used the 10-20 International System of electrode placement. Eighteen channels of EEG were recorded on referential and bipolar montages and were at least 30 minutes long. Hyperventilation was performed in all patients who were old enough to cooperate, and photic stimulation was performed in all patients. The EEG technologist conducted the studies as if they were being recorded on paper, using four predetermined referential and bipolar montages. The technologist changed the filter settings and sensitivity during the recording as necessary. All studies were stored on optical disk. In addition, a proportion of them (n= 57) were also printed on paper. The paper was 21.5 cm in height, and usually at least 16 channels were displayed. One second encompassed 30 mm. The DG32 EEG machine video screen used for all the digital interpretations was 23 cm in width and 18 cm in height (area containing traces). One second encompassed 23 mm.
