Abstract

Desflurane-induced QT prolongation followed by ephedrine-triggered premature ventricular contractions led to torsades de pointes/ventricular fibrillation in two patients. These cases demonstrate sequential electrocardiographic progression and highlight the importance of careful vasopressor selection during general anesthesia.
