Methadone-induced torsade de pointes.

摘要

Torsade de pointes is a rare but life-threatening ventricular dysrhythmia that has been associated with numerous medications. We present a case of polymorphic ventricular tachycardia in a 55-year-old man on methadone. The patient's QTc interval normalized after discontinuation of the methadone. Emergency physicians should be aware of this potential adverse effect from methadone.
