What is an ECG test (electrocardiogram)?

An ECG test – also known as an electrocardiogram – can help with the diagnosis of many conditions affecting the heart.

Your doctor might want to monitor your heart to look for irregular heart rhythms or any signs of heart disease. The ECG test records electrical signals of the heart over a short period.

An ECG test is quick and easy to perform, taking approximately five minutes.

What happens in an Holter EKG?

During an ECG test, small and sticky electrode patches will be placed on your arms, legs and chest. A wire connects the electrodes to an ECG monitor which will pick up and record the electrical signals produced by each heartbeat. You will not feel anything and there will be no pain or discomfort during the ECG test.

Preparing for an ECG test

  • Please inform Express Diagnostics (link to contact page) if you are allergic to Elastoplast.
  • We recommend that you wear a two-piece outfit with a loose top to the ECG test, as you will need to remove your top. We also recommend not wearing tights because an electrode will be placed onto the ankles.
  • Please do not use cream or talcum powder on your chest area on the day of the ECG test, as this may make it more difficult to stick the electrodes to your chest.

What to expect at the ECG test

This is what will happen at your holter EKG test:

  1. You will be asked to strip to your waist.
  2. A Health Care Assistant will put some small sticky patches called electrodes on to your chest to detect your heart’s electrical signals. Some men may need small areas of their chest shaved to help the electrodes stick properly.
  3. The electrodes will then be connected with wires to a recording machine.
  4. You will be asked to sit or lie still while the ECG test machine picks up and records the electrical signals produced by each heartbeat.

When will I get my ECG results?

Your doctor will talk to you about getting the results. They may call you in for a further appointment if necessary.
