HG - Atrial Fibrillation - Primary

Atrial Fibrillation at [[Hospital Name]]

When your heart is beating normally, you may never even notice it. The two small chambers of the heart, called the atria, fill with blood and then contract to push the blood into the larger bottom chambers, called the ventricles.

But in some cases, the heart begins to beat irregularly — sometimes due to a condition called atrial fibrillation or AFib. AFib occurs when the upper chambers of the heart beat irregularly. When this happens, the atria cannot effectively push blood into the ventricles, disrupting blood flow to the entire body.

In many instances, people with AFib may experience no symptoms at all. But others may also experience a wide range of symptoms, including:

  • Chest pain
  • Dizziness
  • Fainting
  • Heart palpitations
  • Shortness of breath
