Some people with atrial fibrillation (AF) have no symptoms and are unaware of their condition until it's discovered during a physical examination. Those who do have AF symptoms may experience signs and symptoms such as:
- Palpitations, which are sensations of a racing, uncomfortable, irregular heartbeat or a flip-flopping in your chest
- Reduced ability to exercise
- Shortness of breath
- Chest pain
If you have any symptoms of AF, make an appointment with your doctor. Your doctor may order an electrocardiogram to determine if your symptoms are related to AF or another heart rhythm disorder (arrhythmia).
If you have chest pain, seek emergency medical assistance immediately. Chest pain could signal that you're having a heart attack.
