To maximize the efficiency of diagnostic video/EEG telemetry, we retrospectively studied the occurrence of clinical events during admission in 254 patients. One hundred fifty-nine patients had psychogenic nonepileptic seizures (PNES) and 95 had epileptic seizures (ES). Twenty-five with PNES and none with ES had an event before or during electrode placement (P<0.0001). In the remaining 229, the initial event occurred within 48 hours of electrode placement in 98.5% patients with PNES and 100.0% of patients with ES. Time to occurrence of initial event did not differ between groups (P=0.69). 17.1% patients with PNES and 51.6% with ES had events between 12 AM and 6 AM (P=0.001). In conclusion, during diagnostic video/EEG telemetry, most patients who experience PNES or ES have diagnostic, typical events within 2 days. Although time to initial event after electrode placement does not differ between diagnoses, events prior to or during placement are most likely PNES and events at night are most likely ES.
为了最大限度地提高诊断性视频/EEG 遥测的效率，我们回顾性地研究了 254 名住院患者的临床事件发生情况。159 名患者患有心因性非癫痫性发作（PNES），95 名患者患有癫痫发作（ES）。25 名患有 PNES 的患者和没有患有 ES 的患者在电极放置前或期间发生了事件（P<0.0001）。在其余的 229 名患者中，PNES 患者中有 98.5%和 ES 患者中有 100.0%的初始事件发生在电极放置后 48 小时内。两组之间初始事件发生的时间没有差异（P=0.69）。17.1%的 PNES 患者和 51.6%的 ES 患者在上午 12 点至凌晨 6 点之间发生了事件（P=0.001）。总之，在诊断性视频/EEG 遥测期间，大多数经历 PNES 或 ES 的患者在 2 天内出现诊断性、典型的事件。尽管电极放置后初始事件发生的时间在不同诊断中没有差异，但在放置前或期间发生的事件很可能是 PNES，夜间发生的事件很可能是 ES。
