The test is performed to evaluate the heart's function, by viewing its electrical activity.

What is the test?

An electrocardiogram (ECG or EKG) is a painless, non-invasive test whereby the doctor visualizes the electrical impulses of your heart. A technician will place a total of approximately 10 electrode patches on the skin of your arms, legs and chest (sometimes it is necessary to shave small areas of body hair in order to get a good reading). These electrode patches are hooked up to an electrocardiography machine which displays the electrical activity of your heart.

This test can give your doctor the following information about the functioning of your heart:

• Heart attack: EKGs show whether you are currently having a heart attack or have had one in the past and can help distinguish between chest pain (angina) and a heart attack.
• Heart rate and rhythm: EKGs exhibit how fast or slow your heart is beating, and if the beats are regular or irregular.
• Heart structure: EKGs may indicate the size of your heart and if a particular part of your heart is being worked too hard.

Where is the test performed?

In the Meriter Heart Hospital or in your physician's office.

How long does this test take?

Approximately 5 minutes.
