Atrial Fibrillation

Abnormal Heartbeat that Affects Blood Flow in Your Heart

What is Atrial Fibrillation?

Atrial fibrillation, also known as "AFib or AF," is the most common type of irregular heartbeat. This occurs when the blood from the upper chambers of your heart (atria) doesn't flow as it should to the lower chambers of your heart (ventricles). Patients often describe this condition as feeling like they have a fluttering in their chest, but some people never feel any symptoms at all. Common symptoms of atrial fibrillation include:


  • Chest Pain
  • Extreme Fatigue
  • Heart Palpitations
  • Irregular Heartbeat
  • Lightheadedness
  • Shortness of Breath

Risk Factors

  • Coronary Artery Disease
  • Excessive Alcohol Use
  • Heart Attack
  • Heart Failure
  • Hypertension
  • Hyperthyroidism

Treatment for atrial fibrillation will depend on a variety of factors after an examination by your Mercy Health physician, which may include an EKG or ECG. Based on the severity of your atrial fibrillation, your provider will suggest medications, a non-surgical procedure or surgery as the best course of action.
