|
Definition
| a portable electrocardiograph worn by the patient that monitors electrical activity of the heart over 24 hours - useful in detectnig periodic abnormalities |
|
|
Term
| intracardiac electrophysiological study (EPS) |
|
Definition
| invasive procedure involving placement of catherter-guided electrodes within the heart to evaluate and map the electrical conduction of cardiac arrhythmias; intracardiac catheter ablation may be performed at the same time to treat the arrhythmia |
|
|
Term
| intracardiac ctaheter ablation |
|
Definition
| use of radiofrequency waves sent through a catheter within the heart to treat arrhythmias by selectively destroying myocardial tissue at sites generating abnormal electrical pathways |
|
|
Term
| magnetic resonance angiography (MRA) |
|
Definition
| magnetic resonance imaging of the heart and blood vessels for evaluation of patholgy |
|
|
Term
| nuclear medicine imaging of the heart |
|
Definition
| radionuclide organ imaging of the heart after administration of radioactive isotopes to visualize structures and analyze functions |
|
|
Term
| myocardial radionuclide perfusion scan |
|
Definition
| 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 |
|
|
Term
| myocardial radionuclide perfusion stress scan |
|
Definition
| 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 |
|
|
Term
| positrom emission tomography scan of the ehart (PET) |
|
Definition
| use of nuclear isotopes and computed tomography techniques to produce perfusion (blood flow) images and study the cellular metabolism of the heart; can be taken at rest or with stress |

Definition
|
|
Term
|
Definition
| introduction fo 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 chamber so fht eheart and coronary arteries-very often includes interventional procedures such as angioplasty and atherectomy |
|
|
Term

|
Term
|
Definition
| measurement of the volume percentage of left ventricular contents ejected with each contraction |
|
|
Term
|
Definition
| recording of sound waves through the heart to evaluate structure and motion |
|
|
Term
|
Definition
| an echocardiogram of the heart recorded during the induction fo 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 - useful in detecting conditions such as ischemia and infarction |
|
|
Term

|
|
Term
|
Definition
| 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. |
|
|
Term
