which drug is preferred for atrial fibtillation : digoxin or cardioselective beta blocker?

Selective B B is prefered as AF has to be corrected immidiatoly other wise it can land up in to VT .
Digoxin take 3 wk to become at therapatic level though it is more useful but due to time delay B B prefered.


B blockers control atrial rate in AF
Digoxin merely prevents ventricular tachy by blocking AV conduction but AF remains unaffected.
