What typically occurs when atrial flutter is successfully terminated?

• A. Patient remains in atrial flutter
• B. Transition back to normal sinus rhythm
• C. Patient experiences ventricular fibrillation
• D. Patient goes into atrial fibrillation

Answer: (B)

When atrial flutter is successfully terminated, the typical outcome is a transition back to normal sinus rhythm. This is primarily due to the fact that atrial flutter is a re-entrant atrial tachycardia, often caused by a circuit in the right atrium. Successful termination usually involves disrupting this circuit, which re-establishes normal electrical conduction in the atria, thereby allowing for the heart to resume its regular sinus rhythm. The underlying mechanism involves the restoration of coordinated atrial contraction and subsequent normal rhythm propagation through the AV node to the ventricles. This process is crucial for maintaining efficient heart function and blood flow. While other possibilities like remaining in atrial flutter or transitioning to atrial fibrillation exist, they do not represent a typical outcome of successful termination efforts. Ventricular fibrillation is not a direct consequence of terminating atrial flutter either; it constitutes a separate and distinct cardiac emergency. Thus, the reversion to normal sinus rhythm is the desired and most common result following successful intervention for atrial flutter.
