Indications for intervention in AF post cardiac surgery according to the ACC/AHA/ESC guidelines

Indication Class I	Unless contraindicated, tretment with an oral beta-blocker drug to prevent POAF is recommeded for patients undergoing cardiac surgery.	Level of Evidence: A
	Administration of AV nodal blocking agents is recommended to archieve rate control in patients who develop POAF.	Level of Evidence: B
Indication Class IIa	Preoperative administration of amiodarone reduces the incidence of AF in patients undergoing cardiac surgery and represents appropriate prophylactic therapy for patients at high risk for POAF.	Level of Evidence: A
	It is reasonable to restore sinus rhythm by phramacologic cardioversion with ibutilide or direct- current cardioversion in patients who develop POAF, as advised for nonsurgical patients.	Level of Evidence: B
	It is resonable to administer antiarrhythmic medications in an attempt to maintain sinus rhythm in patients with recurrent of refractory POAF, as recommended for other patients who develop AF.	Level of Evidence: B
	It is reasonable to administer antithrombotic medication in patients who develop POAF, as recommended for nonsurgical patients.	Level of Evidence: B
Indication Class IIb	Prophylactic administration of sotalol may be considered for patients at risk of developing AF after cardiac surgery.	Level of Evidence: B
