Listen to Dr. deGuzman discuss the success rate of drug therapy with atrial fibrillation.
Drug therapy is successful in controlling the rate of transmission to the ventricles, but overall it is not very effective. About 40% to 60% of patients who are on medical therapy for atrial fibrillation ultimately failed that therapy and required other forms of therapy, either electrical types of therapy with cardioversion, or pacemaker implantation, or a catheter ablation, or even surgical procedures to cure the atrial fibrillation. So, overall, it is not very effective.
