Atrial Fibrillation (AFib)
Description
An irregular and often very rapid heart rhythm (arrhythmia) that can lead to blood clots, stroke, heart failure, and other heart-related complications. During AFib, the heart's two upper chambers (the atria) beat chaotically and irregularly — out of coordination with the two lower chambers (the ventricles).
Common Symptoms
- Heart palpitations (sensations of a racing, uncomfortable, or fluttering heartbeat)
- Weakness
- Reduced ability to exercise
- Fatigue
- Lightheadedness
- Dizziness
- Shortness of breath
- Chest pain
Common Causes
- Abnormalities or damage to the heart's structure are the most common cause. Risk factors include high blood pressure, coronary artery disease, heart valve problems, and an overactive thyroid.
Treatment Information
Treatment aims to reset the rhythm, control the heart rate, and prevent blood clots. This can involve medications, cardioversion procedures, or catheter ablation.
