What happens during an electrocardiogram?

ANSWER

A technician will attach 10 electrodes with adhesive pads to the skin of your chest, arms, and legs. If you're a guy, you may need to have your chest hair shaved to allow a better connection. During the test you'll lie flat while a computer creates a picture, on graph paper, of the electrical impulses that move through your heart. This is called a "resting" EKG, although the same test may be used to check your heart while you exercise. It takes about 10 minutes to attach the electrodes and complete the test, but the actual recording takes only a few seconds. Your doctor will keep your EKG patterns on file so that he or she can compare them to tests you get in the future.
