How do we diagnose Atrial Fibrillation (AF or Afib)?

There are different tests that can be performed to correctly diagnose Atrial fibrillation. All the tests depend of looking at your heart rhythm especially at the times you have symptoms.

  • EKG
  • Holter monitor (24 hours or 48 hours)
  • Event Monitor (30 days)
  • Loop recorder

What if a test was done and nothing was picked up. If you continue to have any symptoms then further testing should be done which may include one of the above monitors for a longer period of time or a stress test or echocardiogram.
