Physical effects of atrial fibrillation

A fluttering heart beat is the most common symptom of atrial fibrillation.

The physical effects of atrial fibrillation can include:

  • chest pain
  • fatigue (tiredness)
  • shortness of breath
  • rapid, strong or irregular heartbeat

Increased risk effects of atrial fibrillation

Atrial fibrillation increases the risk of stroke, especially in people who:

  • are over 65 years old
  • have had a stroke before
  • have high blood pressure, diabetes or heart failure
    • this is when the pumping action of the heart is not strong enough to move blood around
      • it can lead to a build-up of fluid in the lungs or surrounding body tissues

As well, blood clots can form in the heart’s top 2 chambers if blood does not completely empty. A blood clot could break away and travel to the brain, causing a stroke.

If you have atrial fibrillation, you should ask your health care provider about how to manage it.
