An arrhythmia is a problem with the speed or rhythm of the heartbeat. Atrial fibrillation (AF) is the most common type of arrhythmia. The cause is a disorder in the heart�s electrical system.
Often, people who have AF may not even feel symptoms. But you may feel
- palpitations -- an abnormal rapid heartbeat
- shortness of breath
- weakness or difficulty exercising
- chest pain
- dizziness or fainting
AF can lead to an increased risk of stroke. In many patients, it can also cause chest pain, heart attack, or heart failure.
Doctors diagnose AF using family and medical history, a physical exam, and a test called an electrocardiogram (EKG), which looks at the electrical waves your heart makes. Treatments include medicines and procedures to restore normal rhythm.

All medicines have benefits and risks. The risks of medicines are the chances that something unwanted or unexpected could happen to you when you use them, such as Atrial Fibrillation. Side effects can be temporary or long-lasting, and vary in seriousness. It is important to monitor drugs for Atrial Fibrillation and any other side effects. Sometimes Atrial Fibrillation can be reduced with the right treatment.
