Diagnostic tests and imaging to aid diagnosis

Diagnostic tests and imaging are fundamental for diagnosing and managing cardiac problems. The test results and scans help create an image of each patient’s heart to help guide what our cardiologists, cardiac surgeons, and electrophysiologists do next. We only work with the most advanced cardiac imaging equipment, provided through the most comprehensive private cardiac diagnostics network in the UK. And it’s why the teams behind the equipment – from physiologists to reporting clinicians – are leaders in their field. 

At HCA UK you can get test results within 48 hours * of your visit to us. 

Cardiac tests and heart scans at HCA UK

Blood pressure monitoring

Ambulatory blood pressure monitoring is a non-invasive way of recording your blood pressure over 24 hours or longer. 

Ajmaline provocation test


An ajmaline challenge is a diagnostic procedure to detect Brugada syndrome, a rare but serious electrical heart disorder

Holter Monitor Test


An electrocardiogram monitor measures and records your heart's rate and rhythm for a period of 24 hours to seven days

Bubble contrast echocardiogram


A specialised cardiac ultrasound study, used to detect connections between the right and left side of the heart

Cardiac CT scan

CT coronary angiogram with calcium scoring. A cardiac CT scan offers a non-invasive technique to evaluate the heart arteries and structure of the heart using X-rays.

Cardiac MRI scan

Magnetic resonance imaging (MRI) of the heart. A cardiac MRI creates detailed pictures of your heart and major blood vessels to help diagnose and treat heart problems.

Specialist cardiac teams behind the machines

Our technicians, physiologists, reporting clinicians and radiologists are all specialists — using our machines to get the most precise information possible. Many even super-specialise in particular diagnostic tests, technology and analysis.

Our imaging teams have introduced diagnostic technologies to the UK, like FFRct technology. Some have even introduced world-first technologies, like applying state-of-the-art bioengineering techniques to cardiac CT. Our consultants work with research institutions, lead panels to evaluate new technology, and are internationally recognised teachers in the field — one has founded the largest CT training academy in Europe.

In multi-disciplinary team meetings, imaging teams present patients’ results and discuss them with a room of senior clinicians. All the expertise in the room is channelled into choosing the best treatment for each patient.

Getting the right diagnosis first time


Every day our technicians run tests like echocardiography, CT, MR and PET scans for patients. Our technology gives us the fastest, highest-definition 3D images possible.

Blood tests

A blood test can tell your consultant all about your heart muscle, enzymes, proteins and cholesterol. Our perfusionists even perform blood tests during operations to predict how a patient might respond to treatment inside and outside the operating theatre.

Electrocardiogram (ECG) Test


An ECG is a simple and non-invasive test to assess heart rate and rhythm and diagnose or monitor heart conditions

Cardiac Stress Test


A stress test or exercise tolerance test gives information about how your heart functions under the strain of exercise
