He has been experiencing episodes of racing heartbeat, accompanied by dizziness, lightheadedness, chest palpitations, and, sometimes, fainting for the past several months. The man states that the palpitations can occur at any time and that he manages to control them by holding his breath for a long time. He has no family history of heart disease. Previous ECG examination showed a shortened PR interval, a widened QRS complex, and a delta wave. His blood pressure is 100/70 mm Hg, and his pulse is 180/min. Cardiac monitoring shows atrial fibrillation. He is given an antiarrhythmic, reverts to sinus rhythm, but then develops ventricular fibrillation. Which of the following drugs would be most appropriate to prevent ventricular fibrillation in this patient?
A. Adenosine
B. Digoxin
