INTRODUCTION The availability of ambulatory EEG-video monitoring gives an alternative to traditional inpatient EEG-video, but its yield and diagnostic value are not well known. This study evaluates the yield of ambulatory EEG-video for the diagnosis of epilepsy. METHODS We retrospectively reviewed the ambulatory EEG-video monitoring data from 200 consecutive and unselected patients aged 12 years and older performed by a single company (RSC Diagnostic Services) between January 2018 and May 2018. Studies were processed by two senior certified long-term monitoring EEG technologists and interpreted by neurologists. RESULTS Of the 200 patients, 130 (65%) were women, mean age was 45 years. Mean duration of studies were 76.6 hours (range 23-175 hours). There were 110 studies (55%) with events recorded and 101 (92%) were captured on video. Epileptic events accounted for 17.8% (18/101) of the events captured and 9% (18/200) of our total cohort. Nonepileptic diagnosis accounted for 38% of the total number of patients in study (76/200). CONCLUSION Ambulatory EEG-video monitoring may be a useful alternative to inpatient epilepsy monitoring unit, particularly with high clinical suspicion for nonepileptic events.

动态脑电图视频监测的产量

简介 动态脑电视频监测的可用性为传统住院脑电视频提供了替代方案，但其产量和诊断价值尚不为人所知。本研究评估了动态脑电图视频对癫痫诊断的价值。方法 我们回顾性审查了 2018 年 1 月至 2018 年 5 月期间由一家公司（RSC 诊断服务）执行的 200 名 12 岁及以上连续和未经选择的患者的动态脑电图视频监测数据。研究由两名资深认证的长期监测处理脑电图技术专家和神经学家解释。结果 200 名患者中，130 名（65%）为女性，平均年龄为 45 岁。平均研究时间为 76.6 小时（范围 23-175 小时）。有 110 项研究 (55%) 记录了事件，101 项 (92%) 被记录在视频中。癫痫事件占捕获事件的 17.8% (18/101) 和我们总队列的 9% (18/200)。非癫痫诊断占研究患者总数的 38% (76/200)。结论 动态脑电图视频监测可能是住院癫痫监测单元的有用替代方案，特别是临床高度怀疑非癫痫事件的情况。
