Atrial Fibrillation. Atrial fibrillation (A-tre-al fi-bri-LA-shun), or AF, is the most common type of arrhythmia (ah-RITH-me-ah). An arrhythmia is a problem with the rate or rhythm of the heartbeat. During an arrhythmia, the heart can beat too fast, too slow, or with an irregular rhythm. Atrial Fibrillation (AF). Atrial fibrillation, or AF, is the most common type of arrhythmia An Introduction to the Causes of Atrial Fibrillation. The causes of atrial fibrillation aren't always known, and many people who develop the condition already live a healthy lifestyle and don't have any other health concerns. In most cases, however, the cause is known. Some of the more common atrial fibrillation causes include: 1  Heart problems. 2  Surgery.  1 6 diseases that are common. 2  1 disease that is uncommon. 3  3 diseases that are very rare. 4  72 diseases without any prevalence information. 5  The following drugs, medications, substances or toxins may possibly cause Atrial fibrillation as a side effect. The following causes of Atrial fibrillation are diseases or medical conditions that affect more than 10 million people in the USA: 1  Coronary heart disease. 2  Diabetes Mellitus. 3  Hypertension, systemic. 4  Ischaemic heart disease. 5  more causes...». The symptoms are generally the same; however the duration of the AFib and underlying reasons for the condition help medical practitioners classify the type of AFib problems. The most common symptom: a quivering or fluttering heartbeat Atrial fibrillation (AFib) is the most common type of irregular heartbeat. The abnormal firing of electrical impulses causes the atria (the top chambers in the heart) to quiver (or fibrillate). View an animation of atrial fibrillation. Additional common symptoms of atrial fibrillation Sometimes people with AFib have no symptoms and their condition is only detectable upon physical examination. Still, others may experience one or more of the following symptoms: 1  General fatigue. 2  Rapid and irregular heartbeat. 1 4 diseases that are very common. 2  6 diseases that are common. 3  1 disease that is uncommon. 4  3 diseases that are very rare. 5  72 diseases without any prevalence information. 6  The following drugs, medications, substances or toxins may possibly cause Atrial fibrillation as a side effect. The following causes of Atrial fibrillation are diseases or medical conditions that affect more than 10 million people in the USA: 1  Coronary heart disease. 2  Diabetes Mellitus. 3  Hypertension, systemic. 4  Ischaemic heart disease. 5  more causes...». The following causes of Atrial fibrillation are diseases or conditions that affect more than 1 million people in the USA: 1  Atrial fibrillation. 2  Congenital heart defects. 3  Graves' disease. 4  Heart failure. 5  Myocardial infarction. 6  Rheumatic fever. 7  more causes...». The following causes of Atrial fibrillation are diseases or medical conditions that affect more than 10 million people in the USA: 1  Coronary heart disease. 2  Diabetes Mellitus. 3  Hypertension, systemic. 4  Ischaemic heart disease. 5  more causes...». It is extremely rare for atrial fibrillation to develop in younger patients, unless they have an underlying heart condition. Experts say there are many cases in which the cause of the atrial fibrillation was never found. Here is a list of the most common causes: 1  Hypertension-high blood pressure. 2  Coronary artery disease-also known as coronary heart disease. 3  Plaque builds up inside the coronary arteries.
