What is Atrial Fibrillation?

Atria Fibrillation (also known as AF) is an irregular rapid heart rhythm which affects the upper chambers of the heart. The upper chambers quiver instead of pumping normally and this affects the blood being pumped around the body efficiently. A normal heart rate beats approximately 60-100 beats per minute.
You can test your heart rate by feeling for the pulse in your neck or wrist.
Your doctor will use an electrocardiogram (ECG) or a Holter monitor to determine whether or not you have AF.

  • Heart sensations, sometimes called palpitations, which may include irregular, thumping, or pounding heartbeat
  • A feeling that your heart is racing
  • Chest discomfort or pain
  • Fainting or light-headedness
  • Fatigue, shortness of breath, or weakness
