  1. auscultation
    a physical examination method of listening to sounds within the body with the aid of a stethoscope
  2. bruit
    noise; an abnormal heart sound caused by turbulence within
  3. gallop
    an abnormal heart sound that mimics the gait of a horse; related to abnormal ventricular contraction
  4. electrocardiogram (ECG/EKG)
    an electrical picture of the heart represented by positive and negative deflections on a graph labeled with the letters P,Q,R,S and T, corresponding to events of the cardiac cycle
  5. stress electrocardiogram
    an ECG of the heart recorded during the induction of controlled physical exercise using a treadmill or ergometer (bicycle)
  6. Holter ambulatory monitor
    a portable electrocardiograph worn by the patient that monitors electrical activity of the heart over 24 hours
  7. intracardiac electrophysiological study (EPS)
    invasive procedure involving placement of catheter-guided electrodes within the heart to evaluate and map the electrical conduction of cardiac arrhythmias
  8. intracardiac catheter ablation
    use of radiofrequency waves sent through a catheter within the heart to treat arrhythmias by selectively destroying mycardial tissue at sites generating abnormal electrical pathways
  9. magnetic resonance angiography (MRA)
    magnetic resonance imaging of the heart and blood vessels for evaluation of pathology
  10. nuclear medicine imaging of the heart
    radionuclide organ imaging of the heart after administration of radiactive isotopes to visualize structures and analyze functions
  11. myocardial radionuclide perfusion scan
    a scan of the heart made after an intravenous injection of an isotope that is absorbed by myocardial cells in proportion to blood flow throughout the heart
  12. myocardial radionuclide perfusion stress scan
    a nuclear scan of the heart taken after the induction of controlled physical exercise via treadmill or bicycle or administration of a pharmaceutical agent that produces the effect of exercise stress in patients unable to ambulate
  13. positron emission tomography (PET) scan of the heart
    use of nuclear isotopes and computed tomography techniques to produce perfusion (blood flow) images and study the cellular metabolism of the heart
  14. angiography
    an x-ray of a blood vessel after injection of contrast medium
  15. angiogram
    a record obtained by angiography
  16. coronary angiogram
    an x-ray of the blood vessels of the heart
  17. arteriogram
    an x-ray of a particular artery
  18. aortogram
    an x-ray of the aorta
  19. venogram
    an x-ray of a vein
  20. cardiac catheterization
    introduction of a flexible, narrow tube or catheter through a vein or artery into the heart to withdraw samples of blood, measure pressures within the heart chambers or vessels, and inject contrast media for fluoroscopic radiography and cine film (motion picture) imaging of the chambers of the heart and coronary arteries
  21. left heart catheterization
    an x-ray 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
    an x-ray visualizing the ventricles
  24. stroke volume (SV)
    measurement of the amount of blood ejected from a ventricle in one contraction
  25. cardiac output (CO)
    measurement of the amount of blood ejected from either ventricle of the heart per minute
  26. ejection fraction
    measurement of the volume precentage of left ventricular contents ejected with each contraction
  27. echocardiography (ECHO)
    recording of sound waves through the heart to evaluate structure and motion
  28. stress echocardiogram (stess ECHO)
    an echocardiogram of the heart recorded during the induction of controlled physical exercise via treadmill or bicycle or administration of a pharmaceutical agent that produces the effect of exercise stress in patients unable to ambulate
  29. transesophageal echocardiogram (TEE)
    an echocardiographic image of the heart after placement of an ultrasonic transducer at the end of an endoscope inside the esophagus
  30. Doppler sonography
    an ultrasound technique used to evaluate blood flow to determine the presence of a deep vein thrombosis (DVT) or carotid insufficiency, or flow through the heart, chambers, valves, etc.
