Auricular fibrillation

Auricular Fibrillation is a medical condition characterized by irregular and often rapid heart rate that can increase the risk of strokes, heart failure and other heart-related complications. It is also known as atrial fibrillation or AFib.

Causes

Auricular fibrillation can be caused by various factors such as high blood pressure, coronary artery disease, heart attacks, abnormal heart valves, congenital heart defects, an overactive thyroid or other metabolic imbalances. Other possible causes include exposure to stimulants such as medications, caffeine, tobacco or alcohol, sick sinus syndrome, viral infections, stress due to surgery, pneumonia or other illnesses.

Symptoms

Symptoms of auricular fibrillation can include heart palpitations, shortness of breath and weakness. Other symptoms may include fatigue, lightheadedness, confusion, chest pain or fainting. However, some people with auricular fibrillation have no symptoms and are unaware of their condition until it's discovered during a physical examination.

Diagnosis

Auricular fibrillation is usually diagnosed during a physical examination through the use of electrocardiogram (ECG) tests, Holter monitors, event recorders, echocardiograms, blood tests, stress tests, and chest X-rays.

Treatment

Treatment for auricular fibrillation can involve medication, electrical shock (cardioversion), surgery or catheter procedures. The goal of treatment is to reset the rhythm or control the rate of the heart beat and prevent blood clots, which can reduce the risk of strokes.

Prognosis

The prognosis for individuals with auricular fibrillation varies depending on the individual's overall health, the presence of other heart diseases, and how well the condition is managed.
