Question | Answer |
---|---|
aneurysm | Localized abnormal dilation of a vessel, usually an artery |
arrest | Condition of being stopped or bringing to a stop |
cardiac | Loss of effective cardiac function, which results in cessation of circulation |
circulatory | Cessation of the circulation of blood due to ventricular standstill or fibrillation |
arrhythmia | Inability of the heart to maintain a normal sinus rhythm, possibly including a rapid or slow beat or “skipping” a beat; also called dysrhythmia |
bruit | Soft blowing sound heard on auscultation, possibly due to vibrations associated with the movement of blood, valvular action, or both; also called murmur |
cardiomyopathy | Any disease or weakening of heart muscle that diminishes cardiac function |
catheter | Thin, flexible, hollow plastic tube that is small enough to be threaded through a vein, artery, or tubular structure |
coarctation | Narrowing of a vessel, especially the aorta |
deep vein thrombosis (DVT) thromb: blood clot | Blood clot that forms in the deep veins of the body, especially those in the legs or thighs |
ejection fraction (EF) | Calculation of how much blood a ventricle can eject with one contraction |
heart failure (HF) | Failure of the heart to supply an adequate amount of blood to tissues and organs |
embolus embol: embolus (plug) | Mass of undissolved matter (foreign object, air, gas, tissue, thrombus) circulating in blood or lymphatic channels until it becomes lodged in a vessel |
fibrillation | Quivering or spontaneous muscle contractions, especially of the heart, causing ineffectual contractions |
hemostasis | Arrest of bleeding or circulation |
hyperlipidemia lipid: fat | Excessive amounts of lipids (cholesterol, phospholipids, and triglycerides) in the blood |
hypertension (HTN -tension: to stretch | Common disorder characterized by elevated blood pressure persistently exceeding 140 mm Hg systolic or 90 mm Hg diastolic |
primary | HTN in which there is no identifiable cause; also called essential hypertension |
secondary | HTN that results from an underlying, identifiable, commonly correctable cause |
hypertensive heart disease | Any heart disorder caused by prolonged hypertension, including left ventricular hypertrophy, coronary artery disease, cardiac arrhythmias, and heart failure |
implantable cardioverterdefibrillator (ICD) | Implantable battery-powered device that monitors and automatically corrects ventricular tachycardia or fibrillation by sending electrical impulses to the heart |
infarct | Area of tissue that undergoes necrosis following cessation of blood supply |
ischemia | Local and temporary deficiency of blood supply due to circulatory obstruction |
mitral valve prolapse (MVP) | Common and occasionally serious condition in which the leaflets of the mitral valve prolapse into the left atrium during systole causing a characteristic murmur heard on auscultation |
radioisotope | Chemical radioactive material used as a tracer to follow a substance through the body or a structure |
palpitation | Sensation that the heart is not beating normally, possibly including “thumping,” “fluttering,” “skipped beats,” or a pounding feeling in the chest |
patent ductus arteriosus | Failure of the ductus arteriosus to close after birth, allowing blood to flow from the aorta into the pulmonary (lung) artery |
perfusion | Circulation of blood through tissues or the passage of fluids through vessels of an organ |
tetralogy of Fallot | Congenital anomaly consis. of 4 elements: 1 pulmonary artery stenosis; 2 interventricular septal defect; 3 transposition of the aorta, so both ventricles empty into the aorta; 4 right ventricular |
stent | Slender or threadlike device used to hold open vessels, tubes, or obstructed arteries |
thrombus | Blood clot that obstructs a vessel |
