Atrial fibrillation is a common arrhythmia, difficult to treat pharmacologically and associated with significant morbidity and mortality. Although traditionally prescribed when pharmacologic therapy is not effective, not tolerated, or contraindicated, electrical therapy should no longer be considered as a treatment of last resort. Implantable devices such as cardiac pacemakers and internal defibrillators capable of monitoring atrial tachyarrhythmias have enhanced understanding of the mechanisms and natural history of atrial tachyarrhythmias. This knowledge allows electrical therapy to alter the natural course of atrial tachyarrhythmias early after onset or create an unfavorable electrophysiological environment in circumstances predisposing to their initiation. Thus, electrical therapies are playing an increasingly important role in the overall management of atrial fibrillation and tachyarrhythmias, often in combination with antiarrhythmic drugs and sometimes with other strategies....
