Atrial fibrillation, known as AF or Afib, is an irregular and often very fast heart rate. This may cause symptoms like heart palpitations, fatigue, and shortness of breath. Treating atrial fibrillation is important because it may cause a stroke and negatively impact your quality of life. While the condition isn’t considered life-threatening, people with AF are five to seven times more likely to form blood clots and suffer a stroke. Fortunately, AF may be treated with medication, cardioversion (a special type of electric shock), surgical procedure or catheter ablation procedure.
Atrial fibrillation occurs when the upper chambers of the heart, or atria, fibrillate. This means that they beat very rapidly and irregularly. Blood is not pumped efficiently to the rest of the body which may cause you to feel weak or tired, or to experience uncomfortable heart sensations like a racing or irregular heartbeat.
There are different types of atrial fibrillation:
The causes of atrial fibrillation are often unclear. In some cases, the causes of atrial fibrillation are a heart abnormality from birth or damage to the heart structure from a heart attack or heart valve problem. People with otherwise normal hearts may also develop atrial fibrillation.
Some people experience these symptoms of atrial fibrillation:
Others have no symptoms and discover that they have atrial fibrillation at a doctor’s appointment. Even without symptoms, atrial fibrillation is a serious medical condition. Treating AF may prevent stroke, fatigue, and heart failure.
Make an appointment with your doctor if you have symptoms of atrial fibrillation. He or she may be able to confirm or rule out AF.
To help prevent atrial fibrillation, some risk factors may be controlled or modified.
