Q: Following of which is the immediate drug of choice to treat ventricular tachycardia (V.Tach.) induced from Digitalis toxicity? - choose one

A) B- blocker
B) Calcium Channel Blocker
C) Amiodarone
D) Phenytoin
E) Quinidine


Answer: Phenytoin

Actually - Beta-blocker, Calcium Channel Blocker, Quindine and Amiodarone should be avoided in Digitalis induced ventricular tachyarrhythmias as they may exacerbate it.

In above situation either Phenytoin or Lidocaine should be the drug of treatment.
