Seizure duration was estimated using a single channel EEG recording during ECT. Seizure endpoint was defined as the point of last spike. Three psychiatrists independently rated forty seven EEG records. Seizure endpoint could be reliably identified. The reliability coefficient between three raters was 0. 92, indicating high agreement among raters. Modal difference between any pair of raters as well as all three was 0.5 second or less. Operational definition of seizure endpoint improves the reliability of identifying the same and hence estimation of seizure duration from even a single channel EEG trace.
使用 ECT 期间的单通道 EEG 记录估计癫痫发作持续时间。癫痫发作终点定义为最后一个尖峰的点。三位精神科医生独立评估了 47 份 EEG 记录。可以可靠地识别癫痫发作终点。三位评估者之间的可靠性系数为 0.92,表明评估者之间具有高度一致性。任何两位评估者之间以及所有三位评估者之间的模态差异均为 0.5 秒或更短。癫痫发作终点的操作定义提高了识别相同终点的可靠性,从而即使仅从单通道 EEG 轨迹也可以准确估计癫痫发作持续时间。
