In managing a patient with atrial fibrillation, which treatment is NOT appropriate?

In managing a patient with atrial fibrillation, the choice of treatment should be focused on rate control, rhythm control, and preventing thromboembolic events. While heparin is often used in certain situations, particularly for patients in acute atrial fibrillation who are at risk for thrombus formation, it is not universally the first-line choice for antithrombotic therapy.

The primary goal in the acute management of atrial fibrillation is to prevent stroke due to thrombus formation in the left atrial appendage. Anticoagulation is essential, but the preferred agents are typically vitamin K antagonists (like warfarin) or direct oral anticoagulants (DOACs) rather than heparin alone. Heparin may be used if immediate anticoagulation is needed, but it is not considered the long-term or most effective antithrombotic treatment for atrial fibrillation.

In contrast, treating the underlying disease can help manage the overall condition, electrical cardioversion is a common procedure used to restore normal heart rhythm, and intravenous digoxin can be utilized in certain scenarios, particularly for rate control, although it is not the first-line agent in many cases due to its slower onset of action.
