Without any treatment, atrial fibrillation can occur as a problem by itself that is, unrelated to any other heart condition or disease. In such cases, it can be treated with medication or with catheter ablation by a cardiac electrophysiologist or with a surgical procedure by a cardiac surgeon. Atrial fibrillation is also associated with chronic fatigue and heart failure where the heart is unable to pump enough blood to the other organs. Fortunately, these risks can be reduced dramatically if they are monitored and treated. By working closely together, patients and doctors can choose the most appropriate course of care for the atrial fibrillation treatment.
