[Powerlessness and apathy in digitalis intoxication].

A 85 year old female was hospitalized because of a bronchopulmonary infection. During the hospitalization she developed a progressive stupor. There was no sign of an intracerebral pathology, an electrolyte disorder, a new infection or a psychiatric diagnosis. Evaluation of the past history made a recently started digitalis medication responsible for the stupor. After discontinuation of digitalis the patient regained complete consciousness within two weeks. In the Holter-EKG we found once an asystole of four seconds duration without any symptoms.
