Electrocardiogram (ECG)

An electrocardiogram (ECG) is a test that records the electrical activity of the heart. The test is used to measure any damage to the heart, how fast the heart is beating and whether it is beating normally. It can also be used to determine the effects of heart medications and devices. You may need an ECG if you are experiencing chest pain, have an upcoming surgery or have a history of heart disease.

During this simple and painless test, electrodes are connected to several parts of your body. You then lie still and breath normally while the device records your heart’s electrical activity.
