Which of the following drugs is administered intravenously for the treatment of Paroxysmal Supraventricular Tachycardia
Show Hint
Adenosine is the "Reset Button" for a racing heart in PSVT.
Updated On: May 15, 2026
- Adenosine
- Prazosin
- Nifedipine
- Bepridil
Show Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Step 1: Concept
Paroxysmal Supraventricular Tachycardia (PSVT) is a rapid heart rhythm originating above the ventricles.
Step 2: Meaning
Intravenous administration is required for rapid-acting antiarrhythmic effects to terminate the acute episode.
Step 3: Analysis
Adenosine is a short-acting nucleoside that slows conduction through the AV node, making it the drug of choice for acute PSVT. Prazosin is an alpha-blocker, and Nifedipine/Bepridil are calcium channel blockers with different primary uses.
Step 4: Conclusion
Adenosine's unique mechanism and ultra-short half-life make it the standard IV treatment for PSVT. Final Answer: (a)
