CH. 10: Cardiovascular Diagnostic Terms

Question 1

angiography

RI [blood vessels]

Answer 1

radiographic imaging of blood vessels (the procedure is named for the vessel to be studied)

Question 2

angioscopy

Answer 2

visual examination (of the inside) of a blood vessel

Question 3

aortogram

Answer 3

radiographic image of the aorta (after an injection of contrast media)

Question 4

arteriogram

Answer 4

radiographic image of an artery (after an injection of contrast media)

Question 5

venogram

Answer 5

radiographic image of a vein (after an injection of contrast media)

Question 6

coronary angiography
(IP, catheter [inserted –> artery in g, a, or n; advan. –> coronary vessels], cm inject, images recorded; best technique [deter. % of blockages –> coronary arteries])

Answer 6

an invasive procedure in which a catheter is inserted into an artery in the groin, arm or neck, then advanced into the coronary vessels; next, contrast media are injected, and images are recorded; considered the best technique for determining the percentage of blockages in the coronary arteries.

Question 7

magnetic resonance angiography (MRA)

Answer 7

a noninvasive procedure that does not require catheterization and uses specialized MR imaging to study vascular structures of the body; may be chosen over computed tomography angiography because there is no exposure to ionizing radiation.

Question 8

computed tomography angiography (CTA)

Answer 8

a noninvasive procedure that uses a high-resolution CT system to study vascular structures of the body after the injection of intravenous contrast media.

Question 9

digital subtraction angiography (DSA)

Answer 9

an invasive procedure in which an image is taken and stored in the computer, then contrast medium is injected; a second image is taken and stored in the computer; the computer compares the two images and subtracts the first image from the second, removing structures not being studied; enables better visualization of the arteries than regular angiography.

Question 10

echocardiogram (ECHO)

Answer 10

record of the heart (structure and motion) using sound waves; used to detect valvular disease and evaluate heart function.

Question 11

electrocardiogram (ECG, EKG)

Answer 11

record of the electrical activity of the heart

Question 12

electrocardiography

Answer 12

process of recording the electrical activity of the heart

Question 13

cardiologist

Answer 13

physician who studies and treats diseases of the heart

Question 14

cardiology

Answer 14

study of the heart; a branch of medicine that deals with diseases of the heart.

Question 15

electrophysiologist

Answer 15

a cardiologist who specializes in the diagnosis and treatments of patients with arrhythmias .

Question 16

atrioventricular (AV)

Answer 16

pertaining to the atrium and the ventricle

Question 17

intravenous (IV)

Answer 17

pertaining to within the vein

Question 18

cardiogenic

Answer 18

originating in the heart

Question 19

intravenous (IV) therapy

Answer 19

the infusion of a substance directly into a vein for therapeutic purposes
