TY - JOUR PY - 1995// TI - Case report: reversible QT prolongation with torsades de pointes in a patient with pimozide intoxication JO - American journal of the medical sciences A1 - Krähenbühl, S.

SP - 315 EP - 316 VL - 309 IS - 6 N2 - Pimozide is a diphenylpiperidine neuroleptic with well characterized cardiovascular side effects including QT prolongation. So far, life-threatening cardiac arrhythmias, in particular torsades de pointes, have not been described in patients treated with pimozide. The authors describe a patient in whom torsades de pointes developed after the ingestion of 800 mg pimozide as a suicide attempt. After intravenous treatment with lidocaine and magnesium, the patient recovered completely and the QT interval had normalized 5 days after the intoxication. Potential mechanisms leading to torsades de pointes in patients treated with pimozide are discussed.
