title: A comparison of standard alternating current and low-energy brief-pulse electrotherapy.
abstract: This study compares a low-energy brief-pulse stimulus (LEBS) with a conventional a-c sine wave stimulus in terms of electrical paramenters, efficiency in producing seizures, and clinical outcome on a variety of standard behavioral measures. The results show the LEBS to require equal voltage, less current, and only one-half the total energy to produce clinically manifest convulsions. There was no apparent difference between methods on any outcome measure. The Halstead-Reitan Neuropsychological Test Battery showed as many patients impaired prior to ECT as following treatment. Implications for ECT practices are discussed.
