Ans: B. Adenosine
(Ref Harrison 191E, p1480 184,7)1882)
- The given ECG is showing atrial fibrillation.
- Adenosine is used in the treatment of PS VT, not in atrial fibrillation
β-blockers (Metaprolol) can be used to reduce the ectopics that initiate AF and are the usual first line therapy.
Amiodarone is also effective prevents episodes.
Rate control – β-blockers and rate-limiting calcium antagonists (e.g. verapamil, Diltiazem) are more effective at controlling heart rate during exercise
Adenosine plays an important role in energy transfer (adenosine triphosphate or ATP) and in cellular signaling (cyclic AMP).
The cardiovascular uses of adenosine relate to its ability to block the AV Node.
