Write answer in between .Q:A 63-year-old man with a history of hypertension and atrial fibrillation is brought into the emergency room and found to have a ventricular tachyarrhythmia. Ibutilide is discontinued and the patient is switched to another drug that also prolongs the QT interval but is associated with a decreased risk of torsades de pointes. Which drug was most likely administered in this patient?? A: Sotalol, B: Digoxin, C: Esmolol, D: Amiodarone, E: Quinidine,  <response>: This is a clinical vignette about a 63-year-old man with hypertension, atrial fibrillation, and ventricular tachyarrhythmia who was initially given ibutilide but then switched to another QT-prolonging drug with lower torsades risk. Ibutilide is an antiarrhythmic that can be used to treat atrial fibrillation, but it carries a risk of QT prolongation and torsades de pointes. The question is asking which QT-prolonging antiarrhythmic would be a safer choice in this patient after ibutilide was stopped. Sotalol A is a beta blocker with Class III antiarrhythmic properties that can prolong the QT interval and cause torsades. Digoxin B does not prolong the QT interval.Esmolol C is an ultra-short acting beta blocker that does not prolong the QT interval. Amiodarone D is a Class III antiarrhythmic that can prolong the QT interval but carries a lower risk of torsades compared to other QT-prolonging drugs.Quinidine E is a Class Ia antiarrhythmic that can prolong the QT interval and cause torsades.D: Amiodarone
