Our Services
Comprehensive Cardiac Testing
Different cardiac tests help assess different aspects of heart health. Your clinician can recommend the test most appropriate for your symptoms and medical history.
Stress Testing
A supervised exercise or medication-based test evaluates how the heart responds to increased workload when clinically appropriate.

Echocardiogram
An ultrasound examination creates images of the heart to help assess its structure, pumping function and movement of its valves.

Holter Monitoring
A portable ECG device records heart rhythm continuously over an extended period, commonly 24–48 hours or as prescribed.

Why Cardiac Testing?
Better Understanding of Your Heart Health
Cardiac diagnostic tests provide different types of information about how your heart works. When selected by a qualified clinician, these tests can support further assessment, diagnosis and treatment planning.
- Rhythm assessment: ECG and Holter monitoring can help evaluate irregular heartbeats.
- Heart structure and function: Echocardiography provides ultrasound images of the heart.
- Exercise response: Stress testing assesses the heart under a controlled increase in workload.
- Informed next steps: Your clinician interprets findings alongside your symptoms and history.
Know Your Test
Cardiac Tests Explained
Learn what each test generally involves. The actual procedure and preparation depend on the test prescribed for you.
Electrocardiogram (EKG/ECG)
Small electrodes are placed on the skin to record the heart's electrical signals. The test is usually quick and painless. It may be used when assessing palpitations, chest discomfort or other symptoms.
Stress Testing
Heart rhythm, blood pressure and symptoms may be monitored while you exercise on a treadmill or receive medication that simulates the effects of exercise. Follow the specific instructions provided by your clinician.
Echocardiogram
A sonographer or clinician uses ultrasound to create moving images of the heart. A standard transthoracic echocardiogram is generally non-invasive and does not use ionising radiation.
Holter Monitoring
A small portable monitor records heart rhythm during everyday activities for the prescribed monitoring period. You may be asked to keep a symptom diary and follow instructions about bathing and device care.

Frequently Asked Questions
Questions About Cardiac Diagnostics
Find answers to common questions about cardiac testing. Contact the centre if you need test-specific instructions.
An ECG records the electrical activity of
your heart through electrodes attached to
the skin. It is commonly used to assess
heart rate and rhythm. Your clinician will
explain whether it is appropriate for you.
A standard transthoracic echocardiogram is
generally painless. A clinician applies gel
to the chest and moves an ultrasound probe
over the area to obtain heart images.
Monitoring commonly lasts 24–48 hours, but
the duration may vary depending on the
device and your clinician's instructions.
You will be told when to return the monitor.
Appointment requirements depend on the
specific test and the centre's schedule.
Please contact the centre in advance to
confirm availability, preparation and
whether a prescription is required.
No single test detects every heart
condition. The appropriate investigation
depends on symptoms, medical history and
clinical assessment. Your clinician may
recommend additional tests if needed.
