What is ECG?

An electrocardiogram (e-lek-tro-KAR-de-o-gram), also called an EKG or ECG, is a simple, painless test that records the heart's electrical activity. To understand this test, it helps to understand how the heart works. With each heartbeat, an electrical signal spreads from the top of the heart to the bottom.

An ECG records the electrical activity of the heart. The heart produces tiny electrical impulses which spread through the heart muscle to make the heart contract. These impulses can be detected by the ECG machine. You may have an ECG to help find the cause of symptoms such as the feeling of a 'thumping heart' (palpitations) or chest pain. Sometimes it is done as part of routine tests - for example, before you have an operation.

The ECG test is painless and harmless. (The ECG machine records electrical impulses coming from your body - it does not put any electricity into your body.)
