Electrocardiogram (ECG)		Exercise (Treadmill) Test
An ECG is a quick, easy test that records the electrical signals generated by the heart with each heart beat.		This is the most widely used screening test for cardiac disease, and is an important and accurate way of assessing how the heart works when placed under a 'load'.
Echocardiography (ECHO)		24-hour Ambulatory Blood Pressure Unit (ABU)
Echocardiography is a non-invasive technique to look at the structure and function of the heart.		An ambulatory monitor takes about 40 BP readings over 24 hours, and can show the maximum, minimum and average BP at different times of the day.
24 or 48-Hour (Holter) ECG Monitor		Exercise Stress Echocardiography
A holter monitor records the heartbeat continuously for 24 to 48 hours.		The stress echo is a combination of an exercise test and an echocardiogram. Its main purpose is to derive information about the coronary arteries non-invasively
Dobutamine Stress Echocardiogram (DSE)		Transoesophageal Echocardiography (TOE)
This test is similar to an exercise stress echo, but is used for people with known or suspected coronary disease who are unable to cope with an exercise test for any reason.		A TOE is an echocardiogram obtained from a probe passed through the mouth to the oesophagus (gullet). This gives very high quality images, particularly of the structures at the back of the heart.
Myocardial Perfusion Scan		Abdominal Aortic Ultrasound
Myocardial perfusion imaging is a non-invasive diagnostic test to compare the blood flow to the heart muscle (myocardium) at rest and under conditions of stress (usually an exercise test).		Ultrasound is a good method for looking at the aorta in most people, and can pick up the presence of plaque and its complications.
Renal Duplex Ultrasound		Carotid Duplex Ultrasound
This test is used to look at the size and shape of the kidneys, and their blood vessels (the renal arteries). The test is often performed in people with newly diagnosed high blood pressure.		The carotid arteries can be seen easily by non-invasive ultrasound scanning, which is a good method for detecting the presence of plaque and for calculating the degree of narrowing.
Cardiovascular Magnetic Resonance Imaging (Cardiac MRI)		CT Coronary Angiogram
Cardiac MRI is a relatively new method of imaging the heart and blood vessels that is non-invasive and does not use radiation (like X-rays).		CT coronary angiography is a modern form of non-invasive angiography that takes X-ray pictures of cross-sections of the heart (like slices of bread) very quickly.
Cardiac (coronary) Angiography
Angiography is the demonstration of the anatomy and abnormalities of the arteries and veins in all regions of the body.
