Epileptic spasms (ES) are the ictal manifestation of West syndrome. Due to poor interrater reliability in diagnosing hypsarrhythmia, identification of ES - ideally on video EEG monitoring - is important to start proper treatment.
We retrospectively analyzed inpatient video EEG recordings of 42 patients with new onset ES and calculated the time needed to capture the first ES, along with time to first sleep epoch, among other data.
The average time to capture ES was 188.36 min with a 95 percent confidence interval from 116.95 to 259.76 min. The average onset of sleep occurred at 30.8 min with 95% Confidence interval between 19.9 and 41.9 min. There was no significant correlation between duration of symptoms and etiology and the time needed to detect first spasm on EEG.
Routine or short duration EEGs are not sufficient to capture ES in most patients. 4-5-hour VEEG monitoring duration should be considered to capture ictal data in patients suspected of having ES.
癫痫性痉挛（ES）是韦斯特综合征的发作表现。由于在诊断高峰节律紊乱方面评分者间可靠性较差，理想情况下通过视频脑电图监测来识别ES对于开始恰当治疗很重要。
我们回顾性分析了42例新发ES患者的住院视频脑电图记录，并计算了捕捉到首次ES所需的时间，以及首次睡眠时段的时间等数据。
捕捉到ES的平均时间为188.36分钟，95%置信区间为116.95至259.76分钟。睡眠的平均开始时间为30.8分钟，95%置信区间在19.9至41.9分钟之间。症状持续时间和病因与脑电图检测到首次痉挛所需时间之间无显著相关性。
常规脑电图或短程脑电图不足以在大多数患者中捕捉到ES。对于疑似患有ES的患者，应考虑4至5小时的视频脑电图监测时长以捕捉发作期数据。
