aneurysm
localized abnormal dilation of a vessel, usually an artery
arrest
condition of being stopped or bringing to a stop
cardiac arrest
loss of effective cardiac function
circulatory arrest
cessation of the circulation of blood due to ventricular standstill or fibrillation
arrhythmia
inability of the heart to maintain a normal sinus rhythm
bruit
soft blowing sound heard on auscultation; 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)
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
mass of undissolved matter circulating in blood or lymphatic channels
fibrillation
quivering or spontaneous muscle contractions, especially of the heart
hemostasis
arrest of bleeding or circulation
hyperlipidemia
excessive amounts of lipids in the blood
hypertension (HTN)
common disorder characterized by elevated blood pressure persistently exceeding 140 mmHg systolic or 90 mm Hg diastolic
primary hypertension
HTN in which there is no identifiable cause; also called essential hypertension
secondary hypertension
HTN that results from an underlying, identifiable, commonly correctable cause
hypertensive heart disease
any heart disorder caused by prolonged hypertension
implantable cardioverter-defibrillator (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
