Electrocardiogram (ECG)
An electrocardiogram, abbreviated as ECG, is a painless and quick examination that records the electrical activity of the heart. Each time the heart beats, an electrical signal is generated and spreads through the heart muscle. This signal ensures that the heart contracts at the right moment and pumps blood around the body.

Why is an ECG performed?
An ECG is often used to:
- detect heart rhythm disorders.
- check the heart rate and rhythm.
- recognise signs of a heart attack (past or recent).
- check the functioning of a pacemaker.
- establish a baseline in case of heart-related symptoms, prior to surgery.
How does the examination proceed?
- You remove clothing from your upper body.
- The doctor or nurse places ten small suction electrodes on your skin.
- The electrodes are connected to a device that records the signals.
- You lie still for about half a minute while the ECG is recorded.
- The electrodes are then removed and the examination is complete.
