Diagnosis

Question 1

Passage of a catheter into the heart through a vessel to inject a contrast medium for imaging, diagnosis, obtaining samples, or measuring pressure

Answer 1

cardiac catheterization

Question 2

Pressure in the superior vena cava

Answer 2

central venous pressure (CVP)

Question 3

The photographic recording of fluoroscopic images of the heart and large vessels using motion picture techniques

Answer 3

cineangiocardiography

Question 4

An imaging method used to study the rate and pattern of blood flow

Answer 4

Doppler echocardiography

Question 5

A portable device that can record from 24 hours to 1 month of an individual’s ECG readings during normal activity

Answer 5

Holter monitor

Question 6

An amino acid in the blood that at higher-than-normal levels is associated with increased risk of cardiovascular disease

Answer 6

homocysteine

Question 7

Technician who specializes in drawing blood

Answer 7

phlebotomist

Question 8

Electronic recording of heart sounds

Answer 8

phonocardiography

Question 9

Measurement of changes in the size of a part based on the amount of blood contained in or passing through it; impedance plethysmography measures changes in electrical resistance and is used in the diagnosis of deep vein thrombosis

Answer 9

plethysmography

Question 10

Pressure measured by a catheter in a branch of the pulmonary artery. It is an indirect measure of
pressure in the left atrium

Answer 10

pulmonary capillary wedge pressure (PCWP)

Question 11

Imaging of the heart after injection of a radioactive isotope; the PYP (pyrophosphate) scan using technetium-99m (99mTc) is used to test for myocardial infarction because the isotope is taken up by damaged tissue; the MUGA (multigated acquisition) scan gives information on heart function

Answer 11

radionuclide heart scan

Question 12

A cardiac catheter with a balloon at the tip that is used to measure pulmonary arterial pressure; it is flow guided through a vein into the right side of the heart and then into the pulmonary artery

Answer 12

Swan–Ganz catheter

Question 13

Use of an ultrasound transducer placed endoscopically into the esophagus to obtain images of the heart

Answer 13

transesophageal echocardiography (TEE)

Question 14

Simple fat that circulates in the bloodstream

Answer 14

triglyceride

Question 15

X-ray study of the heart’s ventricles after introduction of an opaque dye by means of a catheter

Answer 15

ventriculography
