Atrial Fibrillation

What is AFib?

AFib is when your heart flutters, or beats unevenly. Your heart may beat faster, too.

AFib can lead to a stroke or heart failure.

What does AFib feel like?

Some people do not feel anything or have any problems with AFib. But problems can include:

  1. feeling dizzy or lightheaded
  2. uneven, fluttering, or racing heart beat (palpitations)
  3. feeling weak or tired
  4. chest discomfort or tightness
  5. feeling short of breath
  6. sudden weight gain (examples: 2-3 pounds overnight or 3-5 pounds in a week)

What you can do if you have AFib

  1. Get regular check-ups. Learn about medicines and other treatments.
  2. Check your pulse daily.
  3. Be good to your body.
