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
