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.

  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)
