Quick and effective assessment of your heart rhythm.
Expert cardiology care with a personal approach.
A 12-lead ECG is a simple, non-invasive test that records the electrical activity of your heart.
It is commonly used to assess heart rhythm, detect abnormalities, and investigate symptoms such as chest pain, palpitations or dizziness.
An ECG is often one of the first tests used in cardiac assessment and can provide valuable information quickly.
During your consultation, your cardiologist will:
Small electrodes are placed on your chest, arms and legs
The recording is taken while you lie still for a short time
The test is completed within a few minutes
Your cardiologist will review the results
Where required, further testing such as ECG, echocardiogram or monitoring may be recommended.
Following your consultation, a clear management plan will be provided, and a report will be sent to your referring doctor.
You may be referred for a 12-lead ECG if you experience:
Chest pain
Palpitations
Dizziness or fainting
Shortness of breath
Symptoms requiring routine cardiac assessment
It may also be used as part of pre-operative assessment, general cardiac screening, or follow-up for known heart conditions.

A 12-lead electrocardiogram (ECG) is a quick, non-invasive test that records the electrical activity of your heart. It helps your cardiologist assess your heart rhythm and detect signs of conditions such as arrhythmias, heart attacks, or other cardiac abnormalities.
Small adhesive electrodes are placed on your chest, arms, and legs to measure your heart’s electrical signals. These signals are displayed as waveforms on a monitor or printed on paper for your cardiologist to interpret. The procedure usually takes around 5–10 minutes.
No, an ECG is completely painless. You may feel the coolness of the electrodes or mild pressure when they are applied, but the test does not involve any needles or shocks.
No special preparation is required. You can eat, drink, and take your usual medications before the test. It’s best to wear a loose-fitting top to allow easy access to your chest area.
Once the ECG is complete, your results are reviewed by a cardiologist. Your referring doctor or cardiologist will then discuss the findings with you and determine if any further investigation or treatment is needed.
