Short-breath hold cardiac studies n. |
|
Examination of the heart using an imaging technology -- such as MR or CT -- that requires patients to hold their breath for 10 to 20 seconds to obtain a clearer image.
|
|
Single Photon Emission Computed Tomography (SPECT) n. |
|
Nuclear medicine procedure in which a gamma camera rotates around the patient and takes pictures from many angles, which a computer then uses to create a cross-sectional image.
|
|
|
Imaging method to detect, measure, and characterize tissue at the cellular level. It is used in conjunction with magnetic resonance imaging (MRI), which provides three-dimensional images.
|
|
Stent (uncoated and coated / medicated) n. |
|
Miniscule metal mesh tube, sometimes coated with a drug, that is inserted in a diseased artery to restore blood flow. The stent slowly releases the drug, which is designed to reduce the risk of artery renarrowing.
|
|
Stress test, Echocardiography n. |
|
Test that uses ultrasound waves to create images of the heart at the peak of exercise.
|
|
|
Sudden loss of consciousness, sensation and voluntary motion caused by rupture or obstruction (clot) of a blood vessel of the brain.
|
|
Sudden Cardiac Arrest (SCA) n. |
|
The sudden loss of heart function, which results in death if not promptly treated. The most common cause of SCA is chaotic activity of the heart, called ventricular fibrillation, which prevents the heart from pumping blood effectively. SCA can occur in people of all ages and without warning; in adults, it most frequently strikes patients with coronary heart disease.
