* No specific efforts are made to maintain sinus rhythm
- Prevention of embolic complications
* Antithrombotics
* “Rhythm-control strategy," to restore normal sinus rhythm:
- Antiarrhythmic drugs
- Electrical cardioversion when necessary,

• The most studied anticoagulant drug is unfractioned heparin UFH and, less validated,
subcutaneous enoxaparin.
• In symptomatic patients already taking antivitamin-K, emergency management of
acute AF depends on the INR .

WHICH SUBSET OF AF PATIENTS NEEDS HOSPITAL
ADMISSION?
• Highly symptomatic patients & Poor AF tolerance Specially in Elderly
• Structural heart disease

DISCHARGED FROM THE ED?
