Which medications are commonly prescribed for treating Supraventricular Tachycardia (SVT)?

1. Atenolol/Amiodarone

2. Adenosine/Atenolol

3. Adenosine/Digoxin

4. Atenolol/Adenosine

The correct answer is: Atenolol/Adenosine

The combination of Atenolol and Adenosine is a common approach for treating Supraventricular Tachycardia (SVT). Adenosine is particularly effective as it works rapidly to interrupt the reentrant pathways in the heart that can cause SVT, leading to a prompt decrease in heart rate. It is typically administered as a rapid intravenous push, and its effects are generally felt within seconds. Atenolol, on the other hand, is a beta-blocker that helps to reduce heart rate and exert a calming effect on the heart by blocking the effects of adrenaline. It is generally used for ongoing management of heart rate and rhythm abnormalities, making it a suitable choice for patients who experience frequent episodes of SVT. This combination leverages the immediate action of Adenosine with the longer-term control provided by Atenolol, making it a viable and effective therapy for managing SVT. While other medications listed may have roles in treating various cardiac conditions, the specific action and application of Adenosine and Atenolol align closely with the immediate and preventive needs in SVT management.
