An ECG test takes about 5-10 minutes. Small metal electrodes are placed on your arms, legs and chest. Wires connect these electrodes to the ECG machine. This machine detects the electrical signals that start each heartbeat and records them on paper or a computer.

During the test, you lie quietly on a table while the machine records your heart’s electrical activity. You will need to lie as still as possible, without talking, and breathe normally. After the procedure, the electrodes are removed and discarded. The ECG is painless and harmless.

Why do I need this test?
  • Help find the cause of palpitations or chest pain, dizziness, shortness of breath or fainting
  • Check how well medicines are working and their effect on the heart
  • Check how well mechanical devices that are implanted in the heart, such as pacemakers, are working to control abnormal heart activity
  • Sometimes an ECG is done as part of routine tests, like before an Exercise Tolerance Test or surgical procedure
What to expect?

Ten electrodes are fitted on the chest which will sense the heartbeat.

Your skin will be given a mild exfoliation and wiped with alcohol to facilitate sticking and conduction. You may need to have a small amount of chest hair shaved off. Some people may experience some minor skin irritation from when the electrode is removed.

The procedure requires you to remove the clothing from your upper body.

What do I do during the test?

Once the electrodes are fitted you will be asked to lie still for around 20 seconds whilst the device records your heart.

What are the risks?

This is a very safe non-invasive test. Some patients may experience minor skin irritation from the sticky electrode or preparation, but this is rare.

Is there anything I shouldn’t do during the test?

During the duration of the test, you should not move.
