AbstractTorsades de pointes is a polymorphic ventricular tachycardia that can quickly evolve into ventricular fibrillation and sudden death. This arrhythmia often occurs secondary to medication- induced cardiac repolarization dysfunction with resultant prolonged QTc interval on ECG. Numerous medications can predispose patients to this deadly tachycardia. We report a case of methadone-induced Torsades de pointes complicated by ventricular fibrillation and cardiac arrest. Through rapid taper of methadone, the patient's ECG normalized, allowing for safe discharge. This clinical vignette highlights the importance of close monitoring of patient medications. Performing periodic ECGs with prompt removal of offending agent when repolarization abnormalities are appreciated is ideal. Most importantly, as the vast array of medications continues to grow, it is imperative that clinicians are cognizant of side effects and tailor treatment accordingly.
