title: Torsades de pointes with terfenadine ingestion.
abstract: Torsades de pointes (TDP) is a ventricular tachycardia that can deteriorate into ventricular fibrillation. TDP has been associated with terfenadine use in cases of liver disease, electrolyte abnormalities, concomitant administration of drugs that inhibit cytochrome P-450, or deliberate overdose. This report describes the first case of TDP in a healthy patient taking the recommended therapeutic dosage of terfenadine.
