You would normally get a Holter monitor to wear for about a day at the 10-12 week mark to assess your heart's function. You would not want to be on any heart medication, not rate control (metoprolol, bisoprolol, Sotalol, Diltiazem) nor anti-arrhythmic (flecainide, Multaq, propafenone, amiodarone, Tikosyn..) for about two weeks prior to the Holter because of their potentially lingering effects on your heart's speed and rhythm. IOW, they would mask your heart's real state and the Holter would show that your heart is no longer prone to AF...when it actually IS! So, I hope you get an instruction to taper off amiodarone within the next three weeks. If not, please inquire.
