Write answer in between .Q:A 70-year-old man is brought to the emergency department unconscious after a fall. He appears pale and is pulseless. A 12-lead EKG reveals wide, monomorphic sawtooth-like QRS complexes. He undergoes synchronized cardioversion three times at increasing voltage with no effect. Epinephrine is administered with minimal effect. Which drug will minimize his risk of developing multifocal ventricular tachycardia?? A: Amiodarone, B: Ibutilide, C: Dofetilide, D: Sotalol, E: Procainamide,  <response>: This is a clinical vignette describing a 70-year-old man who is unconscious after a fall. He is pale, pulseless, and has wide, monomorphic sawtooth-like QRS complexes on EKG, indicating ventricular tachycardia. Synchronized cardioversion was ineffective, as was epinephrine. The question asks which drug would minimize his risk of developing multifocal ventricular tachycardia. Amiodarone can be used to treat ventricular tachycardia and prevent recurrence. Ibutilide and dofetilide can convert atrial fibrillation and flutter to sinus rhythm but do not treat ventricular arrhythmias. Sotalol can be used for ventricular arrhythmias but carries a risk of Torsades de Pointes. Procainamide can be used to treat and prevent ventricular tachycardia.Based on the clinical scenario, amiodarone would be the best choice to minimize the patients risk of developing multifocal ventricular tachycardia, as it can both treat the existing ventricular tachycardia and prevent recurrence.A: Amiodarone
