Atrial fibrillation: The two most common causes of atrial fibrillation are hyperthyroidism (overactive thyroid) and degenerative disease of the cardiac conduction system as we get older. Other causes include heart surgery, alcohol (chronic intoxication), and conditions which enlarge the atria (like heart valve problems).
