An investigation of two widely used ECT machines has shown that in one instance the instrument did not meet the manufacturer's specifications, and in both cases ordinary use may increase the possibility of delivering currents which exceed minimal levels necessary to produce a seizure. In the interests of accuracy, efficacy, and sound clinical practice, it is suggested that ECT machines be provided with automatic voltage and timing devices and that professional regulation of such machines be established.
