Atrial fibrillation is an arrhythmia in which the upper chambers of the heart, known as the atria, beat fast and irregularly.


Symptoms of atrial fibrillation include:
• Shortness of breath
• Dizziness
• Chest pain
• Palpitations, or pounding

Sometimes a person will experience no symptoms.


AF is most commonly associated with:
• Advancing age
• High blood pressure
• Heart disease due to other causes such as heart attack, diabetes, congestive heart failure or valve disease
• Aftermath of heart surgery

If AF occurs in people with none of these conditions, it is called “lone” atrial fibrillation.


AF is diagnosed by recording the rhythm of the heart with an electrocardiogram, known as an ECG, or another type of heart monitor. An irregular pulse alone does not indicate atrial fibrillation because such a pulse can be caused by many heart rhythm disorders.


Not everyone with AF requires treatment. Those who do may need medication, including blood thinners to reduce the chance of a stroke. Other treatments such as electrical cardioversion or ablation may be necessary.
