Which medication is typically used to treat ventricular arrhythmia?

• A. Amiodarone
• B. Lidocaine
• C. Dopamine
• D. Propranolol

Answer: (B)

Amiodarone is commonly used to treat ventricular arrhythmias due to its effectiveness in stabilizing heart rhythm and its ability to provide both sodium channel blocking and prolongation of the cardiac action potential. This medication works by slowing down the electrical signals in the heart, which can help to restore a normal heart rhythm in patients experiencing conditions such as ventricular tachycardia or ventricular fibrillation. Lidocaine is another medication used specifically for ventricular arrhythmias, particularly during acute situations, such as ventricular tachycardia. It is an effective antiarrhythmic drug due to its ability to block sodium channels and reduce the excitability of cardiac tissue. Dopamine is primarily used as a inotropic agent to increase heart rate and cardiac output in patients with shock or heart failure, but it does not specifically target ventricular arrhythmias. Propranolol is a beta-blocker used to manage various types of arrhythmias and other conditions like hypertension and anxiety but is not as effective for acute management of ventricular arrhythmias in comparison to amiodarone or lidocaine. Thus, in the context of managing ventricular arrhythmia effectively, amiodarone and lidocaine are the preferred choices, with amiodar
