Which statement about atrial fibrillation treatment is described in the material?

• A. It requires continuous high-energy shock
• B. It uses a low energy defibrillation at a convenient time for the patient
• C. It is managed with observation alone
• D. It is treated with defibrillation only if oxygen is low

Answer: (B)

Restoring rhythm in atrial fibrillation during a monitored sedation scenario is done with a low-energy electrical cardioversion that is delivered in synchrony with the heartbeat, and scheduled at a time that is convenient for the patient. This approach minimizes myocardial stress and reduces the risk of triggering other arrhythmias by ensuring the shock is aligned with the QRS complex. The material describes this as a low-energy, synchronized intervention arranged around the patient’s procedure timing, rather than an immediate, high-energy emergency shock. Relying on observation alone wouldn’t restore the rhythm, and treatment isn’t driven by whether oxygen is low. High-energy, unsynchronized shocks are for ventricular emergencies, not atrial fibrillation.
