(126 cards)
hypertension
high BP
congestive heart failure (CHF)
inability of heart to pump its required amount of blood to meet body’s metabolic demand
angina
chest pain caused by decreased blood flow to the heart
arrhythmia
deviation from normal rhythmic pattern of heartbeat (rrhythm/o)
fibrillation
rapid, involuntary, recurrent contraction of a bundle of nerve fibers or single muscle fiber. results in random inefficient contraction and disruption of normal sinus rhythm; rapid and disorganized
(Acute) Myocardial Infarction
heart attack; necrosis of myocardial muscle due to obstruction in coronary artery caused by atherosclerotic plaque, thrombus or spasm
Flutter
type of arrhythmia characterized by rapid, but regular, contractions of atria or ventricles
atherosclerosis
formation of fatty deposits (ather/o) along inner lining of coronary arteries; caused by hardening, thickening or loss of arterial wall elasticity
-sclerosis
hardening
aneurysm
local widening of artery; can develop from atherosclerosis; sac filled with fluid (clotted blood) formed by dilation of a weakened artery, vein or heart
Acute Coronary Syndrome (ACS)
group of disease changes in coronary arteries that lead to plaque or clot formation and heart attack or other problems
Coronary artery disease (CAD)
any abnormal condition affecting the arteries of the heart; particularly reduced flow of nutrients and O2 to myocardium
Electrocardiography
diagnosis rhythmic irregularities of the hear; records the heart’s electrical activity; establishes diagnosis of congenital heart disease
electrocardiogram
the recording of the ECG
stress test
ECG plus blood pressure monitoring and heart rate measurements showing heart’s response to physical exertion
holter monitor
portable ECG device that can be worn to provide an extended recording of the heart’s activity; also to test the readiness for increasingly challenging exercise regimens
cardiac catheterization
involves guiding a flexible catheter via a vein/artery into heart to detect blood flow and pressure; used to diagnose congential heart disease
cardiac catheter ablation
therapeutic procedure in which catheterization is used to destroy abnormal tissue that is causing arrhythmias
angiography
process of obtaining a radiographic image of blood vessels following injection of contrast dye; to diagnose congenital heart disease
doppler ultrasound
used to measure blood flow (velocity) in vessels via sound waves
echocardiography
use of high-frequency sound waves to show the structure and movement of the heart; also used to diagnose congenital heart failure (CHF)
MUGA scan
shows the motion of the heart wall muscles using radioactive chemicals
treating congenital heart failure (CHF)
take meds to improve pumping action of heart and promote excretion of fluids; restrict sodium and fluid intake
Serum enzyme tests
tests used to determine whether a cardiac infarction has occurred
