Answer 0

abnormal heart sound resembling a galloping horse

Question 1

auscultation

Answer 1

physical examination method of listening to sounds within the body using a stethoscope

Question 2

electrocardiogram (ECG or EKG)

Answer 2

an electrical picture of the heart with the letters P, Q, R, S, & T that corresponds to events in the cardiac cycle

Question 3

stress electrocardiogram

Answer 3

an electrocardiogram of the heart conducted while the patient is physical exercise; useful in detecting heart conditions

Question 4

Holter ambulatory monitor

Answer 4

portable electrocardiograph worn by patients that monitors heart activity for more than 24 hours; useful in detecting periodic anomalies

Question 5

intracardiac electrophysiological study (EPS)

Answer 5

an invasive surgical procedure that places electrodes within the heart to map cardiac arrhythmias

Question 6

intracardiac catheter ablation

Answer 6

use of radiofrequency waves sent through a catheter within the heart to selectively destroy myocardial tissue generating cardiac arrhythmias; done during EPS

Question 7

magnetic resonance angiography (MRA)

Answer 7

MRI of the heart and blood vessels for evaluation of pathology

Question 8

nuclear medicine imaging

Answer 8

radionuclide organ imaging of the heart after administration of a radioactive isotope to view organ structures and analyze function

Question 9

myocardial radionuclide perfusion scan

Answer 9

scan of the heart after IV injection of a radioactive isotope as it is absorbed by myocardial cells in proportion to blood flow throughout the heart; useful in evaluating CAD

Question 10

myocardial radionuclide perfusion stress scan

Answer 10

myocardial radionuclide perfusion scan during excercise

Question 11

multiple-gated acquisition (MUGA) scan

Answer 11

nuclear image of the beating heart in motion made as radioactive isotopes are injected in the bloodstream and traced through the heart chambers.

Question 12

positron-emission tomography (PET) scan of the heart

Answer 12

use of nuclear isotopes and CT techniques to produce blood flow images

Question 13

radiology

Answer 13

x-rays

Question 14

angiography

Answer 14

x-ray of a blood vessel after the injection of a contrast medium

Question 15

angiogram

Answer 15

record of angiography

Question 16

coronary angiogram

Answer 16

x-ray image of the blood vessels of the heart

Question 17

arteriogram

Answer 17

x-ray image of a particular artery

Question 18

aortogram

Answer 18

x-ray image of the aorta

Question 19

venogram

Answer 19

x-ray image of a vein

Question 20

cardiac catheterization

Answer 20

introduction of a catheter through a vessel to the heart to withdraw blood samples, measure blood pressure and inject contrast media

Question 21

left heart catheterization

Answer 21

x-ray imaging of the left ventricular cavity and coronary arteries

Question 22

right heart catheterization

Answer 22

measurement of oxygen saturation and pressure readings of the right side of the heart

Question 23

ventriculogram

Answer 23

x-ray image of the ventricles

Question 24

stroke volume (SV)

Answer 24

measurement of the amount of blood ejected from the ventricle in one contraction

Question 25

cardiac output (CO)

Answer 25

measurement of the amount of blood ejected per minute from either ventricle of the heart

Question 26

ejection fraction

Answer 26

measurement of the volume % of left ventricular contents ejected with each contraction

Question 27

computed tomographic aniography (CTA)

Answer 27

a noninvasive 3D CT scan of the heart and circulation of the greater blood vessels; performed with or without contrast

Question 28

sonography

Answer 28

sonographic imaging

Question 29

echocardiography (echo)

Answer 29

recording sound waves of the heart to evaluate structure and motion

Question 30

stress echocardiogram (stress echo)

Answer 30

echocardiogram of the heart recorded during exercise

Question 31

transesophageal echocardiogram (TEE)

Answer 31

echocardiogram of the heart after placement of an ultrasonic transducer at the end of an endoscope inside the esophagus

Question 32

Doppler sonography

Answer 32

ultrasound technique used to evaluate blood flow and determine the presence of deep vein thrombosis as well as carotoid insufficiency
