Think about this question,
There is a similar question in qbank
This patient may develop Wolf Parkinson White syndrome.
Drug used for WPW: Ia, III, and Flecainide
Drug contraindicated: Beta Blockers, Ca++ blockers, Digoxin
Adenosine is not effective

I think the answer is D. Propanolol, is the drug of choice for Afib, Aflutter and reentry
What suggests WPW??
I agree that adenosin is the DOC for psvt, but not when is stress/excercise related. Usually in critical unit enviroment, _half life is 15 sec.
Lidocaine is DOC for ventricular arrhythmias.
Nifedipine is antianginal.
Quinidine is good for svt, but is usually given to keep Sinus rhythm after cardioversion from a-fib.

correction, nifedipine is peripheric vasodilator.
