Estimates of seizure length made by the treating psychiatrist were compared with estimates made by six-channel EEG in 100 electroconvulsive treatments in 22 depressed patients. In 70 treatments the doctor observed a fit which was shorter than 25 seconds. No doctor restimulated a patient in such a case and on only three occasions was the electrical stimulus increased at the next treatment. EEG monitoring revealed that only 30 of the treatments resulted in a seizure of less than 25 seconds, and this was detected in almost all cases by the treating doctor. The potential value of EEG monitoring was to identify patients whose visible seizure was short but where cerebral seizure length was satisfactory. Trainee psychiatrists often mismanage patients who have short seizures.
在22名抑郁症患者的100次电休克治疗中，将主治精神科医生对癫痫发作时长的估计与六通道脑电图的估计进行了比较。在70次治疗中，医生观察到一次发作时长少于25秒。在这种情况下，没有医生对患者进行再次刺激，并且仅在三次治疗中，在下一次治疗时增加了电刺激。脑电图监测显示，只有30次治疗导致发作时长少于25秒，并且在几乎所有情况下主治医生都检测到了这一点。脑电图监测的潜在价值在于识别那些可见发作较短但脑部发作时长令人满意的患者。实习精神科医生常常对发作时间短的患者处理不当。
