Amiodarone-induced torsade de pointes in a patient with wolff-Parkinson-White syndrome.

Amiodarone is generally regarded to have a high safety profile with a low incidence of arrhythmias. However, there have been reports of torsades de pointes under certain conditions, such as electrolyte imbalance or concomitant antiarrhythmic therapy. We describe a case of amiodarone-induced torsade de pointes early after initiation of intravenous amiodarone in the setting of T-wave alternans.
