What are the symptoms of Atrial Fibrillation (AFib)?


Atrial Fibrillation (AFib) is the most common type of arrhythmia. Whether severe or mild, atrial fibrillation may or may not cause noticeable symptoms. However, when symptoms of AFib occur, they may include:

  • Heart palpitations – pounding, fluttering or racing sensations in the chest
  • Fatigue or Weakness – lack of energy or feeling over-tired
  • Dizziness – feeling light-headed or faint
  • Chest discomfort
  • Shortness of breath


If you’re experiencing any of these symptoms, it’s important to seek evaluation and treatment from a healthcare expert experienced in arrhythmia management. For more about the prevention, symptoms, and risk factors of atrial fibrillation, visit the American Heart Association.
