Many patients with atrial fibrillation have no symptoms and are unaware of the abnormal heart rhythm. The most common symptom of atrial fibrillation is palpitations, an uncomfortable awareness of the rapid and irregular heartbeat. Other symptoms of atrial fibrillation are caused by the diminished delivery of blood to the body. These symptoms include dizziness, fainting, weakness, fatigue, shortness of breath, and angina (chest pain due to reduced blood flow to the heart muscles).
