Answer

Antiarrhythimic drug treatment for 6 weeks after ablation of paroxysmal AF was shown to be well tolerated, to reduce the incidence of clinically significant atrial arrhythmias, and to reduce the need for cardioversion or hospital admission during that period, according to Roux et al. [126] Class IC drugs were used as the first line of therapy, and sotalol was the most commonly used drug in cases of left ventricular dysfunction or coronary artery disease. Measured outcomes included atrial arrhythmias lasting more than 24 hours; atrial arrhythmias associated with severe symptoms that required hospitalization, cardioversion, or initiation/change of antiarrhythmic drug therapy; and intolerance to antiarrhythmic agent requiring drug cessation. [126]
