An electrocardiogram (EKG or ECG) is a test that measures the electrical activity of your heartbeat. With each beat, an electrical pulse travels through the heart. This causes the muscle to squeeze and pump blood from the heart.
More specifically, an EKG can track how long the electrical wave takes to pass through the heart. Finding out how long a wave takes shows if the electrical activity is abnormal. Also, by measuring the amount of electrical activity in your heart, a cardiologist can find out if parts of the heart are too large or are overworked.
The EKG doesn’t send electricity into the body.
An EKG test is sometimes included in a routine exam for middle-aged and older adults because of their higher risk of heart disease.

An EKG test is used to find various heart disorders, including:
You don't need to make any special preparations for an EKG test.
You will be asked to lie down. The health care provider will clean several areas on your arms, legs, and chest and attach small electrodes to those areas. It may be necessary to shave or clip some hair, so the patches stick to the skin.
Wires connect the patches to a machine that turns the heart's electrical signals into wavy lines, often printed on paper. The doctor reviews the test results.
You will need to remain still during the procedure. The provider may also ask you to hold your breath for a few seconds as the test is being done. Any movement can alter the results. However, sometimes this test is done while exercising or under light stress to look for changes in the heartbeat. This type of EKG is called a stress test.
There’s no pain or risk associated with having an electrocardiogram. When the EKG stickers are removed, there may be some minor discomfort.
