Question

Quizplus · Accepted Answer

Dofetilide (Tikosyn) is a class III antiarrhythmic medication that works by prolonging the QT interval. Prolongation of the QT interval can potentially lead to torsades de pointes, a life-threatening arrhythmia. Therefore, monitoring the QT interval is important when administering dofetilide. Monitoring for inverted T waves, widening of the PR interval, and widening of the QRS complex are not typically associated with the use of dofetilide.
