Atrial fibrillation is when the chambers of the heart (the atria) fibrillate (quiver). This can cause a rapid, irregular heart rhythm. This pamphlet reviews the causes and treatment of this heart problem. Catheter ablation is a non-surgical procedure that may be used when medication is not controlling your heart rhythm or symptoms. This pamphlet reviews how catheter ablation is done, risks, what to expect after your procedure, activities to avoid, and signs and symptoms to watch for.
