Atrial Fibrillation Symptoms

Share

You may or may not notice atrial fibrillation. It often occurs with no signs or symptoms. If you do have symptoms, you may only notice atrial fibrillation symptoms occasionally. Or your symptoms may be frequent or serious. If your heart disease is getting worse, you may start to notice more symptoms. Atrial fibrillation that goes undetected or is left untreated can cause serious and even life-threatening complications, including stroke and heart failure.

The most common symptom of atrial fibrillation is fatigue, or extreme tiredness. Other symptoms include:

  • Low blood pressure
  • Difficulty breathing, especially when lying down
  • Chest pain
  • Dizziness or fainting
  • Heart palpitations, or the feeling that your heart is skipping a beat, fluttering, pounding, or beating too hard or too fast

Keep track of when and how often your symptoms occur and what you feel, and note whether these things change over time. They are all important clues to help your healthcare providers diagnose atrial fibrillation.
