Overview

Atrial Fibrillation and Hyperthyroidism

2014 AHA/ACC/HRS Guideline for the Management of Patients With Atrial Fibrillation (DO NOT EDIT)[7]

Class I
"1. Beta blockers are recommended to control ventricular rate in patients with atrial fibrillation complicating thyrotoxicosis unless contraindicated. (Level of Evidence: C)"
"2. In circumstances in which a beta blocker cannot be used, a nondihydropyridine calcium antagonist is recommended to control the ventricular rate. (Level of Evidence: C)"


2011 ACCF/AHA/HRS Focused Updates Incorporated Into the ACC/AHA/ESC 2006 Guidelines for the Management of Patients With Atrial Fibrillation (DO NOT EDIT)[8]

Hyperthyroidism (DO NOT EDIT) [8]

Class I
"1. Administration of a beta blocker is recommended to control the rate of ventricular response in patients with atrial fibrillation complicating thyrotoxicosis, unless contraindicated. (Level of Evidence: B)"
"2. In circumstances when a beta blocker cannot be used, administration of a nondihydropyridine calcium channel antagonist (diltiazem or verapamil) is recommended to control the ventricular rate in patients with atrial fibrillation and thyrotoxicosis. (Level of Evidence: B)"
"3. In patients with atrial fibrillation associated with thyrotoxicosis, oral anticoagulation (INR 2.0 to 3.0) is recommended to prevent thromboembolism, as recommended for atrial fibrillation patients with other risk factors for stroke. (Level of Evidence: C)"
"4. Once a euthyroid state is restored, recommendations for antithrombotic prophylaxis are the same as for patients without hyperthyroidism. (Level of Evidence: C)"
