Electrical measurements were made during treatment of two groups of patients, one group receiving treatment from a constant current ECT machine and the other from a constant voltage machine. The electrical impedance and energy were calculated and compared for the two groups. More energy was delivered by the constant voltage than by the constant current machine, but the spread of energy delivered was comparable. With a consistent technique for applying the electrodes there is little to choose between these machines, but the constant current machine may be preferred where consistency cannot be achieved.
在两组患者的治疗过程中进行了电学测量，一组患者接受恒流电休克治疗机的治疗，另一组接受恒压治疗机的治疗。计算并比较了两组的电阻抗和能量。恒压治疗机传递的能量比恒流治疗机更多，但传递能量的分布情况相当。采用一致的电极应用技术时，这两种机器难分高下，但在无法实现一致性的情况下，恒流治疗机可能更受青睐。
