Hardening of arteries (the most common cholesterol-like deposits (plaque) in arteries)
in the heart, conducts the electrical impulse from the atrioventricular node into the ventricles
neurological tissue in the center of the heart that receives and amplifies the conduction of impulses from the SA node to the bundle of His
bundle of his
specialized conduction tissue in the interventricular septum divides into the right and left branches
smallest blood vessel; brings nutrients and oxygen to the tissues and absorbs carbon dioxide and waste products
a record of the electrical activity of the heart that, if abnormal, may indicate heart disease
a valve in the heart that guards the opening between the left atrium and the left ventricle
normal sinus rhythm
heart rhythm originating in the sinoatrial node with a resting rate of 60 to 100 beats per minute
gas that enters the blood through the lungs and travels to the heart to be pumped via arteries to all body cells
circulation of blood from the pulmonary artery through the vessels in the lungs and back to the heart via the pulmonary vein, providing for the exchange of gases
circulation of blood throughout the body through arteries, arterioles, capillaries, and veins to deliver oxygen and nutrients to body tissues
puncture of a vein to remove blood, instill a medication, or start an intravenous infusion
angiotensin-converting enzyme; relax blood vessels; blood pressure hypertension and heart failure
pain or discomfort in the chest or adjacent areas caused by insufficient blood flow to the heart muscle and a build up of lactic acid
failure of proper conduction of impulses from SA node through the AV node to the atrioventricular bundle - bundle of His
when the normal rhythmic contractions of the atria are replaced by rapid, irregular twitching of the muscular heart wall
A drug that slows heart rate, lowers blood pressure, controls angina and protects patients with prior heart attacks from future heart attacks
calcium channel blocker
Drug used to treat chest pain (angina) and high blood pressure (hypertension).
acute compression of the heart caused by fluid accumulation in the pericardial cavity
procedure to restore normal rhythm of the heart by applying a controlled electrical shock to the exterior of the chest
the process of lameness, limping; may result from inadequate blood supply to the muscles in the leg
coarctation of the aorta
narrowing of the descending portion of the aorta resulting in a limited flow of blood to the lower part of the body
computed tomography angiography
three dimensional x-ray images of the heart and coronary arteries using computed tomography.
congestive heart failure
The inability of the heart to pump a sufficient amount of blood throughout the body, or requiring elevated filling pressures in order to pump effectively
coronary artery bypass graft
surgical technique to bring a new blood supply to heart muscle by detouring around blocked arteries
deep vein thrombosis
formation of a blood clot in a deep vein on the body, occurring most frequently in the iliac and femoral veins.
digitalis preparation (trade name Lanoxin) used to treat congestive heart failure or cardiac arrhythmia
digital subtraction angiography
a process of radiographic imaging of the blood vessels that removes structures not being studied
electron beam computed tomography
Electron beams and CT identify calcium deposits in and around coronary arteries to diagnose CAD
pertaining to the circulation of the blood outside the body via a heart-lung machine or hemodialyze
implantable cardioverter defibrillator
Small electric device implanted inside the chest (near the collarbone) to sense arrhythmia and terminate them to restore normal sinus rhythm.
left ventricular assist device
Booster pump implanted in the abdomen with a tube inserted into the left ventricle. An LVAD is a "bridge to transplant" or destination therapy when heart transplantation is impossible.
percutaneous coronary intervention
a balloon tipped catheter is inserted into a coronary artery to open the artery, stents are put in place
pericardial friction rub
Scraping or grating noise heard on auscultation of the heart; suggestive of pericarditis
positron emission tomography
using a computerized radiographic technique to examine the metabolic activity in various tissues (especially in the brain)
radiofrequency catheter ablation
destruction of abnormal cardiac electrical pathways causing arrhythmias.
technetium 99m sestamibi scan
A radioactive chemical is injected IV and shows perfusion of blood in heart muscle. It is taken up in the area of a myocardial infarction, producing hot spots
therapy consisting of the administration of a pharmacological agent to cause thrombolysis of an abnormal blood clot
