General Cardiac Investigations
Rationale for test
Myocardial Perfusion Study
Stress test for blockages of the heart using special dye and X ray scan.
CT Coronary Angiogram
Non-invasive special X ray scan of the heart for investigation of blockages within the coronary arteries (heart blood vessels). It also measures the calcium score of the coronary arteries which provide important outlook information.
Ultrasound of the heart. Images of cross sectional of the heart are taken, assessing cardiac chamber sizes, wall thickness, velocity and direction of blood flow, ejection fraction (heart pump function) and detect any abnormality of the heart and heart valves.
Treadmill Exercise Stress Test
Determine if there are blockages of the arteries of the heart and also help to evaluate exercise tolerance, BP response, exercise-induced heart rhythm abnormalities.
Ambulatory Blood Pressure (ABP)
Monitor blood pressure at regular interval within 24 hours.
ECG Event Recording
Recording of ECG using a portable device (event recorder) and transmitting to a receiving centre via internet.
Ambulatory monitoring of heart rhythm and rate Detect abnormal heart rhythm Record episodes of chest pain/palpitation/other symptoms.
Assess electrical activity of the heart Arrhythmias ie heart rhythm abnormalities Heart rate Abnormal electrical conduction Ischemia or infarction (heart attack) Abnormalities of the heart (eg heart chamber enlargement).
