In atrial flutter, which treatment is pursued if there are no contraindications?

• A. Cardioversion
• B. Catheter ablation
• C. Acute rate control with beta-blockers or calcium channel blockers
• D. Observation without treatment

Answer: (A)

When atrial flutter is present, the aim is to restore normal atrial rhythm quickly if there are no contraindications to rhythm control. Electrical cardioversion is the fastest and most reliable way to accomplish this, converting the atrial flutter to sinus rhythm in a short, controlled procedure. It provides rapid symptom relief and a high likelihood of immediate restoration of normal rhythm, which is why it’s pursued when eligible. After successful cardioversion, long-term strategies—such as catheter ablation of the flutter circuit—are considered to prevent recurrence, but cardioversion is the first, decisive step for rapid rhythm restoration. Rate-control drugs can manage the heart rate but don’t convert the rhythm, and observation without treatment would leave symptoms and potential complications. Catheter ablation is a highly effective option for definitive treatment, but it’s typically pursued after or in addition to cardioversion, not as the initial maneuver when there are no contraindications.
