How is atrial fibrillation (AFib) diagnosed?

ANSWER

The main thing your doctor wants to see is the electrical activity in your heart. An electrocardiogram (EKG) uses small, sticky sensors placed on your chest to record what's happening.

Your doctor may want you to wear a Holter monitor for a few days while you go about your regular activities. It's like a mobile EKG that continuously records what's going on with your heart, so your doctor can look for signs of an arrhythmia.

If your symptoms come and go, you may need a different kind of monitor for a longer time.
