A patient is having frequent premature ventricular contractions and runs of ventricular tachycardia. Which of the following drugs would be considered for this patient?
1) Procainamide
2) Epinephrine HCl
3) Atropine
4) Amiodarone

Question

Quizplus · Accepted Answer

Procainamide is an antiarrhythmic drug that can be used to treat ventricular tachycardia and frequent premature ventricular contractions by blocking ion channels responsible for the abnormal electrical activity of the heart.

Amiodarone is another antiarrhythmic medication that can help suppress premature ventricular contractions and treat ventricular tachycardia. It works by blocking several types of ion channels in the heart and slowing the electrical activity that can cause arrhythmias.

Epinephrine HCl is not an appropriate treatment for this type of arrhythmia as it can actually worsen the problem.

Atropine is not effective in treating ventricular arrhythmias such as premature ventricular contractions or ventricular tachycardia. It is mainly used to increase heart rate in certain types of bradycardia (slow heart rate) conditions.
