One is aspirin. The other has been Ticlid but most people are now using Plavix instead of Ticlid. After the 2 to 4 week period, aspirin alone is continued indefinitely. There are many new oral antiplatelet agents on the horizon so expect these recommendations to be modified in the future. Clinical circumstances will dictate whether a workup for venous thromboembolic disease or coronary artery disease should be undertaken.
Digoxin takes the longest to slow the ventricular response.
Digoxin will not lower the blood pressure which may or may not be beneficial depending on the patient's blood pressure. For chronic heart rate control, begin p.o. Check rate control during physical activity as well. Digoxin tends to be the least effective at controlling the rate with physical activity. None of these agents are terribly effective at converting the fibrillation back to sinus or preventing recurrent fibrillation in the future.
