Twenty-four h cassette recording (MEDILOG 9000) where obtained in 22 untreated infants (23 records) with a West syndrome (idiopathic: n = 12, symptomatic: n = 10). All these infants had had a 3 h polygraphic recording. Tracings were visually analyzed for sleep stages. Electro-clinical seizures and infraclinical discharges were listed according to their type and the stage of vigilance. Two hundred twenty-eight critical events were recorded in 22 cassette recordings: isolated spasms, clusters of spasms, partial or generalized discharges followed or not by clusters of spasms. Sixty per cent of these fits occurred during wakefulness, 27% during non REM sleep, 13% during awakening and none during REM sleep. Partial discharges, followed or not by clusters of spasms, were only present in cases with unfavourable outcome. In benign spasms the hypsarrhythmic pattern was present between spasms in each cluster, but not in cases with unfavourable outcome. Compared with 3 h polygraphic recordings, 24 h cassette recordings gave supplementary data on the presence, type and timing of seizures in 16 of out 22 cases.
对22例未经治疗的患有韦斯特综合征（特发性：n = 12，症状性：n = 10）的婴儿（23份记录）进行了24小时盒式磁带记录（MEDILOG 9000）。所有这些婴儿都进行过3小时的多导睡眠图记录。对记录进行视觉分析以确定睡眠阶段。根据癫痫发作类型和警觉阶段列出电临床发作和亚临床放电情况。在22份盒式磁带记录中记录到228次危急事件：孤立性痉挛、痉挛簇、伴有或不伴有痉挛簇的部分性或全身性放电。这些发作中60%发生在清醒期，27%发生在非快速眼动睡眠期，13%发生在觉醒期，快速眼动睡眠期未出现发作。伴有或不伴有痉挛簇的部分性放电仅出现在预后不良的病例中。在良性痉挛中，每个痉挛簇的痉挛之间存在高峰节律紊乱模式，但预后不良的病例中不存在。与3小时的多导睡眠图记录相比，24小时盒式磁带记录为22例中的16例提供了关于癫痫发作的存在、类型和时间的补充数据。
