auscultation

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

1

gallop

abnormal heart sound resembling a galloping horse

2

electrocardiogram (ECG or EKG)

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

3

stress electrocardiogram

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

4

Holter ambulatory monitor

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

5

intracardiac electrophysiological study (EPS)

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

6

intracardiac catheter ablation

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

7

magnetic resonance angiography (MRA)

MRI of the heart and blood vessels for evaluation of pathology

8

nuclear medicine imaging

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

9

myocardial radionuclide perfusion scan

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

10

myocardial radionuclide perfusion stress scan

myocardial radionuclide perfusion scan during excercise

11

multiple-gated acquisition (MUGA) scan

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

12

positron-emission tomography (PET) scan of the heart

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

13

radiology

x-rays

14

angiography

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

15

angiogram

record of angiography

16

coronary angiogram

x-ray image of the blood vessels of the heart

17

arteriogram

x-ray image of a particular artery

18

aortogram

x-ray image of the aorta

19

venogram

x-ray image of a vein

20

cardiac catheterization

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

21

left heart catheterization

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

22

right heart catheterization

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

23

ventriculogram

x-ray image of the ventricles

24

stroke volume (SV)

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

25

cardiac output (CO)

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

26

ejection fraction

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

27

computed tomographic aniography (CTA)

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

28

sonography

sonographic imaging

29

echocardiography (echo)

recording sound waves of the heart to evaluate structure and motion

30

stress echocardiogram (stress echo)

echocardiogram of the heart recorded during exercise

31

transesophageal echocardiogram (TEE)

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

32

Doppler sonography

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