title: ECT-induced seizure durations.
abstract: Electroconvulsive therapy (ECT) efficacy is related to the stimulus intensity and clinically associated with the duration of the induced seizure. Convulsions lasting 30 to 60 seconds are conventionally considered to be of optimal length, and generally are achieved by applying routine ECT technique. An ictus slightly shorter or longer is usually also therapeutically satisfactory. In our study, seizures lasting between 30 and 60 seconds produced a favorable clinical outcome. A very similar effect was observed in all cases where the duration was within 16 to 120 seconds. However, subjects experiencing intal periods of less than 15 seconds and those over 120 seconds resulted in less favorable response. Detailed records as to medicinal and electrical stimulus doses, seizure timings, etc, were excellent guides for subsequent ECT to achieve appropriate convulsion durations and a safe, satisfactory outcome.
