The electrocardiogram (ECG) is a test that records electrical signals from your heart. The pattern of these signals can help tell the doctor if your heart is in a normal rhythm, having electrical problems, changes in the heartbeat pattern, strain, heart attack, or other damage.

• Wear loose, comfortable clothing that allows easy access to the chest.
• Allow enough time before your ECG to check in. You'll likely need to fill out paperwork before the test.

• You'll be asked to remove your clothing from the waist up and to put on a gown. You'll then lie down on your back.
• Electrodes (small pads) are placed on your chest, shoulders, and legs. If you have excess body hair that keeps the electrodes from making contact with your skin, small patches of hair may need to be shaved.
• If your skin is moist or sweaty, it may have to be dried off for the small patches to stick to the skin.
• You'll be asked to lie very still and breathe normally while the recording is being taken.
• The electrodes record your heart rhythm and any change in your heart's signals that occur during the test.
• After a few minutes of recording, the doctor will remove the electrodes. In some cases, they may have to repeat the ECG to get accurate results. From start to finish, the ECG takes about 10 minutes.

• You can resume your normal activity.
• The results are sent to your doctor for interpretation.
• Be sure to keep your follow-up appointment.
