terms a-e Flashcards
ejection fraction
a measurement of blood that is pumped out of a filled ventricle. normal is 50 % or more
electroencephalogram (EEG)
a test that can detect and record the brain’s electrical activity. the testis done by pasting metal disks call electrodes onto the scalp
endarterctomy
surgical removal of plaques deposits or blood clots in an artery
endocarditis
a bacterial infection of the heart’s inner lining a (endothelium)
epicardium
the thin membrane covering the outside surface of the heart muscle
exercise stress test
a fairly common test fir diagnosing coronary artery disease, especially in patients who have symptoms of heart disease. the test helps physicians assess blood flow through coronary arteries in response to exercise, usually walking, at varied speeds and for various lengths of time on a tredmill/ a stress test may include use of electrocariography, echocardiography, and injected radioactive substances. also called exercise test, stress test or treadmill test.
coronary arteries
two arteries arising from the aorta that arch down over the top of the heart and divide into branches. they provides blood to the heart muscle
coronary artery bypass (CAB or CABG)
surgical rerouting of blood around a diseased vessel that supplies the heart by grafting either a piece of vein from the leg or the artery from under the breast bone.
coronary artery disease (CAD)
a narrowing of the inside diameter of arteries that supply the heart with blood. the condition arises from accumulation of plaque and greatly increases a person’s risk of having a heart attack
coronary heart disease
disease of the heart caused by atherosclerosis narrowing of the coronary arteries likely to produce angina pectoris or heart attack; general term.
cyroablation
the removal of tissues using an instrument called a cold probe
defibrillator
an electronic device that helps reestablish normal contraction rhythms of a malfunctioning heart.
diabetes mellitus ( DM)
a disease in which the body doesn’t produce or properly use insulin. insulin is needed to convert sugar and starch into energy needed in daily life
diastolic blood pressure
the lowest blood pressure measured in the arteries, it occurs when the heart muscle is relaxed between beats
digitalis
a drug made from the leaves of the foxglove plant. digitalis is used to treat congestive heart failure ( CHF) and heart rhythm problems ( arrhythmia). digitalis can increase blood flow throughout the body and reduce swelling in the hands and ankles.
dissecting aneurysm
a condition in which the layers of an artery seperate and are torn, causing blood flow between the layers. dissecting aneurysms usually happen in the aorta, which is the large vessel that carries blood from the heart to the other parts of t he body
diuretic
a drug that lowers blood pressure by stimulating fluid loss; promotes urine production
doppler ultrasound
a technology that uses sound waves to assess blood flow within the heart and blood vessels and to identify leaking valves.
dysarthria
the imperfect articulation of speech resulting from muscular problems caused by damage to the brain or nervous system.
dyspena
a shortness of breath
echocardiograpy ( ECG)
a method of studying the heart’s structure and function by analyzing sound waves bounced off the heart and recorded by an electronic sensor placed on the chest. a computer processes the information ton produce a one, two, or three dimensional moving picture that shows how the heart and valves are function.
Abdominal aortic aneurysm (AAA)
the name given to an aortic aneurysm occurring below the level of the diagprhm
ablation
elimination or removal
alveoli
air sacs in the lungs where o2 and co2 are exchanged
