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.
