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.

Abnormal heart rhythms or arrhythmias may be asymptomatic or may cause palpitations, blackouts, or breathlessness. Some types of arrhythmia such as atrial fibrillation increase the long term risk of stroke. Some arrhythmias cause the heart to beat abnormally slowly, referred to as a bradycardia or bradyarrhythmia.

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...
See media help. Arrhythmias, also known as cardiac arrhythmias, heart arrhythmias, or dysrhythmias, are irregularities in the heartbeat, including when it is too fast or too slow. [2] A resting heart rate that is too fast – above 100 beats per minute in adults – is called tachycardia, and a resting heart rate that is too slow – below 60 ...

Nov 11, 2022 · What is an Arrhythmia? The term "arrhythmia" refers to any problem in the rate or rhythm of a person’s heartbeat. During an arrhythmia, the electrical impulses may be too fast, too slow or erratic causing an irregular heartbeat. When the heart doesn't beat properly, it can't pump blood effectively.
Overview. What is atrial arrhythmia? Atrial arrhythmias are irregular heartbeats that cause poor circulation. They occur when the upper chambers of your heart are out of rhythm with the lower chambers. This can cause your heart to beat either too fast or slow. These arrhythmias may result from too much caffeine, alcohol or stress.
Although perhaps somewhat of a misnomer, the term cardiac “arrhythmias” (“a” = absence of) is typically used whenever there is any alteration of normal electrical activity (rhythm) of the heart, not necessarily that there is no heart rhythm. An equally descriptive term of “dysrhythmias” (“dys” = abnormal) is also found in the literature.
