Who to See

The following health professionals can detect, diagnose and, in some cases, treat atrial fibrillation:

• General practitioner
• Family doctor
• Internist
• Nurse practitioner (NP)
• Physician assistant (PA)

In general, the extent to which you will need specialized care will depend upon the severity of your symptoms and the complexity of your individual case. Many people who have only mild symptoms or whose arrhythmia is not causing other problems may continue to see their primary care doctors for the ongoing management of the condition.

• Cardiologist.
• Cardiac electrophysiologist.
