A 15 year old girl with a history of childhood absence seizures underwent a prolonged EEG recording. Twelve bursts of 3 Hz generalized spike and wave were recorded during drowsiness and light sleep, all of which were preceded by 14 and 6 Hz positive spikes with a latency of under 1 s. Nine bursts of polyspike-wave, not preceded by 14 and 6 Hz positive spikes, were recorded during deeper sleep (stage 3). The bursts of polyspike-wave were significantly longer when preceded by 14 and 6 Hz spikes than when observed in isolation. The close association between these paroxysmal events in our patient is intriguing, may be coincidental, and has never before been reported.
一名有儿童失神发作病史的15岁女孩接受了长时间的脑电图记录。在嗜睡和浅睡眠期间记录到12阵3Hz的广泛性棘慢波，所有这些发作之前均有潜伏期小于1秒的14Hz和6Hz正相棘波。在深度睡眠（3期）期间记录到9阵多棘慢波，其之前没有14Hz和6Hz正相棘波。当多棘慢波发作之前有14Hz和6Hz棘波时，其持续时间明显长于单独出现时。我们患者中这些阵发性事件之间的密切关联很有趣，可能是巧合，且此前从未有过报道。
