The inter-electrode resistance during ECT is shown to be very variable, a finding which invalidates the measurement of shocks in joules. With square wave pulses of selected current value the threshold for convulsion may be below 100 milliamperes or above 2,000 milliamperes. It is advisable to measure the current value during millisecond pulses with relatively long intervals between.
ECT期间电极间电阻显示出很大的变异性，这一发现使得以焦耳为单位测量电击无效。对于选定电流值的方波脉冲，惊厥阈值可能低于100毫安或高于2000毫安。建议在毫秒脉冲期间测量电流值，且脉冲之间间隔相对较长。
