Seizure durations were determined during electroconvulsive therapy (ECT) by a computer-automated procedure for interpreting electroencephalographic (EEG) and electromyographic (EMG) signals. These seizure durations were compared with durations determined by two experienced clinicians from simultaneous paper recordings of EEG and EMG and with independently recorded observations of cuffed-limb motor movements. The computer EEG seizure end point was programmed as the point where the moving average EEG voltage first fell below the pre-ECT value and remained there for at least 2 s. The computer EMG seizure end point was programmed as the point where the moving average EMG voltage first fell below 200 mV and remained there for at least 2 s. Close correspondence between seizure durations rated from EEG recordings and computer-automated EEG measurements demonstrated validity and high reliability of the computer procedure. Likewise, validity and reliability were demonstrated for motor seizure durations both computer-derived and interpreted from the paper EMG recording by their close correspondence with cuffed-limb motor seizure durations.
在电休克治疗（ECT）期间，通过一种用于解读脑电图（EEG）和肌电图（EMG）信号的计算机自动化程序来确定癫痫发作持续时间。将这些癫痫发作持续时间与两名经验丰富的临床医生根据EEG和EMG的同步纸质记录所确定的持续时间，以及与独立记录的袖带肢体运动观察结果进行比较。计算机EEG癫痫发作终点被设定为移动平均EEG电压首次降至ECT前值以下并持续至少2秒的点。计算机EMG癫痫发作终点被设定为移动平均EMG电压首次降至200 mV以下并持续至少2秒的点。从EEG记录评定的癫痫发作持续时间与计算机自动化EEG测量值之间的密切对应关系证明了该计算机程序的有效性和高可靠性。同样，通过计算机得出的运动性癫痫发作持续时间以及从纸质EMG记录解读的持续时间，与袖带肢体运动性癫痫发作持续时间密切对应，证明了其有效性和可靠性。
