 Epidemiologic studies have shown that 70-80 of patients with atrial fibrillation are older than 65 years of age. Drug therapy for atrial fibrillation is not effective or not tolerated in many elderly patients, for both rate or rhythm strategies. Preliminary data from AVN ablation and pacemaker therapy demonstrated this strategy is highly effective in controlling symptoms among patients who have failed numerous drug therapy. Quality of life is improved while hospital admission and office visits are reduced.
