Non-invasive cardiology tests


Electrocardiograms are used to record the rhythm and electrical activity of the heart.Patients attending a cardiology (heart) outpatient appointment will commonly require one or more of the following tests:

  • ECG (electrocardiogram), which records the rhythm and electrical activity of the heart
  • exercise test (treadmill test)
  • echocardiogram (ultrasound scan), which uses sound waves to produce a detailed picture of the heart
  • cardiac event monitors, which continuously record the rhythm and electrical activity of the heart
  • 24 hour blood pressure monitors, which record the blood pressure for 24 hours
  • stress echocardiogram, which uses ultrasound to examine your heart when it is under stress.

Further tests

In addition, your cardiologist may request any of the following tests:

  • Novacore R-test

    This is both a patient activated and automatic, non-invasive ECG arrhythmia detection device which can be discreetly used to screen for infrequent and/or asymptomatic arrhythmias including those that occur during sleep for up to 32 days.

    This extended monitoring period gives more 'conclusive' results than the traditional 24-hour tape test.

  • Cardiopulmonary exercise testing

    Cardiopulmonary exercise testing (CPET) provides an assessment of exercise responses involving pulmonary, cardiovascular and skeletal muscle systems.

    This information is used to assess suitability for implantable heart failure devices (such as valve replacements), as well as to monitor changes in cardiopulmonary function after an implant.

  • Transoesophageal echocardiogram

    An echocardiogram that involves passing an ultrasound sensor into your oesophagus (the pipe that goes from your mouth to your stomach).

  • Cardiac computed tomography (CT) service 

    Cardiac computed tomography (CT) angiography is a quick non-invasive test that uses x-rays to look at the blood vessels, heart valves and chambers of the heart. Find out more obout our cardiac CT service.

  • Cardiac MRI

    Cardiac magnetic resonance imaging (MRI) uses radiowaves and magnets to create a detailed picture of your heart. Find out more about our cardiac MRI service.
