ECT in a patient with a deep brain-stimulating electrode in place.

A 68-year-old woman had a deep brain-stimulating electrode placed for worsening of a long-standing essential tremor. There is currently no data available on the use of electroconvulsive therapy (ECT) in the presence of the deep brain stimulator (DBS). We report here the successful use of ECT in this patient with no adverse effects to the patient or to the DBS. No special provisions were made with the ECT administration except to ensure that the stimulator was turned off prior to administration of the ECT series, and remained off through the eight treatments administered to this patient. Following the course of treatment, her mood was markedly improved, and she displayed only minor postictal confusion.
