AF Hemodynamically Unstable:
Cardioversion
a)Electrical 100-200 Joules
b)Chemical:Type III Antiarrythmics e.g Sotalol,Amiodarone.
If <48 hrs=Acute
If >48hrs =Chronic =use anticoagulant before cardioversion for a couple of weeks
AF Hemodynamically stable
Rate control: Verapamil/dilitiazem,B-Blockers,Digoxin(Associated with CHF)
Cardioversion
If <48 hrs=Acute
If >48hrs =Chronic =use anticoagulant for a couple of weeks + Rate control as above
Urgent rate control can be accomplished with a beta-blocker, calcium-channel blockers, or digoxin. Digoxin is relatively contraindicated because of the renal insufficiency. In addition, rate control with digoxin takes much more time than using metoprolol. Even intravenously, digoxin can take 6 to 12 hours to be fully effective.
Amiodarone is best used in patients with ventricular dysfunction.

Lone AF have a lower risk than precipating-related AF (of mitral regurgitaion/stenosis...) for coagulation. Aspirrine is appropriate, especially young patient.
