Class I Guidelines
1. Administration of a beta blocker is recommended to control the rate of ventricular response in patients with AF complicating thyrotoxicosis, unless contraindicated. (Level of Evidence: B) [1]
<Poll>
ACC / AHA 2008 guidelines for diagnosis and management of atrial fibrillation: Class I Recommendation 1 for patients with hyperthyroidism should be:
CLASS I
CLASS IIa
CLASS IIb
CLASS III
</poll>
2. In circumstances when a beta blocker cannot be used, administration of a non dihydropyridine calcium channel antagonist (diltiazem or verapamil) is recommended to control the ventricular rate in patients with AF and thyrotoxicosis. (Level of Evidence: B) [1]
<Poll>
ACC / AHA 2008 guidelines for diagnosis and management of atrial fibrillation: Class I Recommendation 2 for patients with hyperthyroidism should be:
CLASS I
CLASS IIa
CLASS IIb
CLASS III
</poll>
3. In patients with AF associated with thyrotoxicosis, oral anticoagulation (INR 2.0 to 3.0) is recommended to prevent thromboembolism, as recommended for AF patients with other risk factors for stroke. (Level of Evidence: C) [1]
