NHS Choices - Symptoms of atrial fibrillation
(24/09/2013)
Some people with atrial fibrillation have no symptoms and it is only discovered during routine tests or investigations for another condition.
The most obvious symptom of atrial fibrillation is becoming aware of a fast and irregular heartbeat (palpitations), usually over 100 beats a minute. You can determine your heart rate by feeling the pulse in your wrist or neck.
You may also experience:
- tiredness
- breathlessness
- dizziness
- chest pain (angina)
The way the heart beats in atrial fibrillation reduces the heart's efficiency and performance. This can result in low blood pressure and heart failure.
If you notice a sudden change in your heartbeat and have chest pain, see your doctor immediately.
