Cardiac Investigations

Cardiac CT

Computer generated X-ray images performed at local radiology sites provides quantification of the degree of coronary artery calcification. When intravenous contrast is also used this allows for the assessment of arterial narrowing.

ECG (Electrocardiogram)

The most widely used investigative tool in cardiology. The ECG represents the hearts' own electrical activity providing insight into a variety of heart conditions.

Holter (24 hour ambulatory ECG) monitoring

Provides ECG information over a 24 hour period.
Allows detection of both fast and slow rhythm disturbances in patients with palpitations, dizziness, blackouts and other intermittent symptoms.

May also detect asymptomatic rhythm abnormalities in patients with known heart disease or prior stroke.

ECHO (Echocardiography)

An ECHO is an ultrasound of the heart, providing detailed images and extensive information on the heart muscle and valve structure and function.
ECHO has many indications, including the investigations of Murmurs (exclude valve disease and structural heart disease), Shortness of Breath (exclude muscle or valve dysfunction), and Hypertension (assess for cardiac hypertrophy and function).


Compares the heart muscle function at rest to that at peak exercise in multiple views.


Stress ECHO is a non-invasive investigation not requiring radiation or intravenous contrast exposure .


The changes seen on Stress ECHO typically occur earlier than Stress ECG changes or symptoms,  are more reliable and localising to the arterial territory,  providing superior accuracy in both detecting, excluding and monitoring coronary artery disease.


The Shire Heart Clinic is a Philips Luminary site and uses their most advanced echocardiogram and experienced sonographers to ensure optimal image quality and cardiac ultrasound assessment.
