Atrial fibrillation (AF, AFib or A-fib) is an abnormal heart rhythm (arrhythmia) characterized by rapid and irregular beating of the atrial chambers of the heart. It often begins as short periods of abnormal beating, which become longer or continuous over time.

Atrial fibrillation is the most common serious abnormal heart rhythm and, as of 2020, affects more than 33 million people worldwide. Treatment of AF includes medications to slow the heart rate to a near-normal range (known as rate control) or to convert the rhythm (beating pattern) to normal sinus rhythm (known as rhythm control).

A heart arrhythmia (uh-RITH-me-uh) is an irregular heartbeat. A heart arrhythmia occurs when the electrical signals that tell the heart to beat don't work properly. The heart may beat too fast or too slow. Or the pattern of the heartbeat may be inconsistent. A heart arrhythmia may feel like a fluttering, pounding or racing heartbeat. Some heart arr...
A heart arrhythmia may not cause any symptoms. The irregular heartbeat may be noticed during a health checkup for another reason. Symptoms of an arrhythmia may include: 1. A fluttering, pounding or racing feeling in the chest. 2. A fast heartbeat. 3. A slow heartbeat. 4. Chest pain. 5. Shortness of breath. Other symptoms may include: 1. Anxiety. 2....
Things that may increase the risk of heart arrhythmias include: 1. Coronary artery disease, other heart problems and previous heart surgery.Narrowed heart arteries, a heart attack, heart valve disease, prior heart surgery, heart failure, cardiomyopathy and other heart damage are risk factors for almost any kind of arrhythmia. 2. High blood pressure...
Complications depend on the type of heart arrhythmia. Possible complications of heart arrhythmias include: 1. Blood clots, which can lead to stroke. 2. Heart failure. 3. Sudden cardiac death. Blood-thinning medicines can lower the risk of stroke related to atrial fibrillation and other heart arrhythmias. If you have a heart arrhythmia, ask a health...
Lifestyle changes used to manage heart disease may help prevent heart arrhythmias. Try these heart-healthy tips: 1. Don't smoke. 2. Eat a diet that's low in salt and saturated fat. 3. Exercise at least 30 minutes a day on most days of the week. 4. Maintain a healthy weight. 5. Reduce and manage stress. 6. Control high blood pressure, high cholester...
Cardiovascular disease ( CVD) is any disease involving the heart or blood vessels. [3] CVDs constitute a class of diseases that includes: coronary artery diseases (e.g. angina, heart attack ), heart failure, hypertensive heart disease, rheumatic heart disease, cardiomyopathy, arrhythmia, congenital heart disease, valvular heart disease ...
Different forms of cardiac arrhythmia shown in an Electrocardiogram. Arrhythmia (commonly called irregular heartbeat) is the name for a number of conditions, where the heartbeat is not normal. It may be too fast (tachycardia); too slow (bradycardia); or the heart may not beat in its regular rhythm. Artificial pacemaker is used to care arrhythmia.
Failure of maintenance of normal sinus rhythm often results in adverse or no heart rhythm, a term referred to as “arrhythmias.”. These can result in the heart rate being too fast (“tachy-”) or too slow (“brady-”) and alter blood flow resulting in patient morbidities and mortalities.

The heart. Blood flow through the valves. As the center focus of cardiology, the heart has numerous anatomical features (e.g., atria, ventricles, heart valves) and numerous physiological features (e.g., systole, heart sounds, afterload) that have been encyclopedically documented for many centuries.
