cardiac catheterization

passage of a catheter into the heart through a vein or artery to provide a comprehensive evaluation of the heart

Holter monitor test

ECG taken with a small portable recording system capable of storing up to 24 hours of ECG tracings

stress test

ECG under controlled exercise stress conditions

nuclear stress test

utilize radioisotope to evaluate coronary blood flow - decreased uptake of the isotope shows area receiving insufficient oxygen

cardiac enzyme studies

blood test that measure troponin T, I and creatinine kinase CK-MB

lipid panel

series of tests (total cholesterol, high & low density lipoprotein, triglycerides) used to assess risk factors of ischemic heart disease

aortography

radiological examination of the aorta and its branches following the injection of a contrast medium via a catheter

coronary angiography

radiological exam of the blood vessels of and around the heart

echocardiography

noninvasive diagnostic method that uses ultrasound to visualize internal cardiac structures and produce images of the heart

Doppler ultrasound

noninvasive adaptation of ultrasound technology in which blood flow velocity is assessed in different areas of the heart- sound waves strike moving red blood cells

magnetic resonance imaging

noninvasive imaging technique using radiowaves and magnetic field rather than an x-ray beam to produce multiplanar cross-sectional images

magnetic resonance angiography

MRI technique used to visualize vascular structures - diagnose aneurysms, occlusions, atherosclerotic plaque, vascular rupture, stenosis

phonocardiography

imaging technique that provides a graphic display of heart sounds and murmurs during the cardiac cycle

subtraction angiography

imaging technique used to display soft tissue structures such as blood vessels without confusing overlay of bone images - subtract image with no contrast from image with contrast
