Atrial fibrillation (AF) is the most frequently diagnosed cardiac rhythm disorder. It affecting 2.5 million people in the United States, and may be associated with an increased risk for death, congestive heart failure, and stroke. Our cardiac electrophysiologist will review the latest treatment options for patients with AF, including recent advances in pharmacologic therapy to keep patients heart rhythms normal. He also will discuss catheter ablation to eliminate sources of AF and anticoagulation to prevent thromboembolic strokes. Presented by Summit Medical Group cardiologist, Roy Sauberman, MD, FACC
