Description of the test

An electrocardiogram is a test that records the electrical activity of the heart. It is useful for diagnosing abnormalities of the heart including heart attacks, abnormal heart rhythms, and other heart conditions.

How often should this test be performed?

Your doctor will decide when and how frequently this test is required.

Why is this test performed?

The electrocardiogram records the underlying rate and rhythm of the heart. It may be performed as part of the routine physical exam or for an exercise stress test. It may also be performed when people have risk factors for heart disease (e.g., diabetes or high blood pressure). Your doctor may also use the test to investigate other conditions.

Electrocardiograms are used when people have symptoms of a heart attack or heart disease (such as chest pain, shortness of breath, or palpitations). They help to identify damage to the heart muscle or enlargement of the pumping chambers of the heart.

Are there any risks and precautions I should know about?

This test is safe. There is no known risk of side effects or complications.

An allergic reaction to the stickers is possible, but rare.
