Asystole is an uncommon but potentially fatal complication of electroconvulsive therapy (ECT). Although the risk of asystole can be reduced with anticholinergic medications, the recent emphasis on new modifications of technique (first, the use of subconvulsive stimuli to titrate the seizure threshold, and second, pretreatment with intravenous beta-blockers) may increase the risk of asystole in ECT patients. ⋯ If risk factors contributing to asystole are reduced and adequate doses of intravenous atropine are on hand, a patient's ECT treatments need not be interrupted.
