A 68 year old male presents to the emergency department complaining of dizziness and palpitations that have been occurring for the past 2 hours. An ECG confirms the presence of atrial fibrillation. The patient has no previous history of atrial fibrillation but was diagnosed with mild aortic valve stenosis 8 months ago during an echocardiogram ordered by his primary care physician. The patient reports that the echocardiogram was done because he was experiencing shortness of breath, which resolved after 2-3 months and was attributed to a recent bout of pneumonia. The decision is made to attempt pharmacological cardioversion. What is the most appropriate medication to use for this purpose in this patient?
