A description is given for the design of an isolated output, servo-controlled voltage, electroconvulsive therapy (ECT) machine for the safe, controlled application of 60-Hz alternating current (ac) signals between 0 and 230 V rms for controlled periods ranging from 0.1 to 2 sec. Added safety is provided by current limiting in the range of 360 to 770 mA rms for patient impedances ranging from 500 to 50 omega. The use of this equipment has permitted a detailed description of the impedances characteristic of unilateral ECT.
本文描述了一种用于电休克治疗（ECT）的机器的设计，该机器具有隔离输出、伺服控制电压，可在0至230V rms的范围内安全、可控地施加60Hz交流（ac）信号，持续时间从0.1秒到2秒不等。对于500至50欧姆的患者阻抗，通过将均方根电流限制在360至770mA的范围内，提供了额外的安全性。使用该设备可以详细描述单侧ECT的阻抗特性。
