What is a common non-pharmacologic treatment for atrial fibrillation?

Electrical cardioversion is a well-established non-pharmacologic treatment for atrial fibrillation. This procedure involves delivering a controlled electric shock to the heart, which helps restore a normal rhythm. It is frequently used in patients experiencing symptomatic atrial fibrillation, particularly when rapid conversion to sinus rhythm is desired, such as in acute cases or when symptoms are significant.

In contrast, other choices like beta-blocker therapy and antiarrhythmic medications are considered pharmacologic treatments. These options involve the use of medications to manage heart rate and rhythm but do not qualify as non-pharmacologic interventions. Cardiac bypass surgery, while a surgical intervention, is typically not directed specifically at treating atrial fibrillation itself, and is more appropriate in situations involving obstructive coronary artery disease or other structural heart problems. Hence, electrical cardioversion stands out as a direct, effective non-pharmacologic method for managing atrial fibrillation.
