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		Event Monitor
A holter monitor records the heartbeat continuously for 24 to 48 hours.		An event monitor, also known as a loop recorder, is a small light weight device connected to electrodes on the patient's chest.
Exercise Stress Echocardiography		Dobutamine Stress Echocardiogram (DSE)
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		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.
Transoesophageal Echocardiography (TOE)		Myocardial Perfusion Scan
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 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).
Abdominal Aortic Ultrasound		Renal Duplex Ultrasound
Ultrasound is a good method for looking at the aorta in most people, and can pick up the presence of plaque and its complications.		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.
Carotid Duplex Ultrasound		Cardiovascular Magnetic Resonance Imaging (Cardiac MRI)
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.		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 Angiogram		Cardiac (coronary) Angiography
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.		Angiography is the demonstration of the anatomy and abnormalities of the arteries and veins in all regions of the body.
