A 35-year-old female alcohol addicted ingested with suicidal intentions a single dose of 500 mg thioridazine. The course of intoxication was complicated by the development of polymorphous ventricular tachycardia of the torsade de pointes type, about six hours after ingestion. The dysrhythmia was immediately suppressed by stimulation from the right atrium. After 36 hours the stimulation could be abolished. Because of delirium tremens the patient with a normal ECG tracing was returned to the psychiatric clinic.
