What is atrial fibrillation?
Atrial fibrillation is an abnormal heart rhythm that causes the upper chamber of the heart to beat in a disorganized manner. This causes the pulse to be irregular and usually rapid.

What are the symptoms of atrial fibrillation?
Common symptoms of atrial fibrillation include rapid pulse, palpitations, dizziness, and weakness. Less commonly seen symptoms are chest pain, breathing difficulty, and fainting.

How does the doctor treat atrial fibrillation?
Treatment for atrial fibrillation may include mediations to control the heart rate or convert the heartbeat to a normal sinus rhythm. Other treatment measures include cardioversion, radiofrequency catheter ablation, and blood thinners to reduce the risk of stroke.
