List of Cardiology Terms(Completely solved)
Ablation correct answersElimination or removal. Also refers to a procedure that eliminates extra
electrical pathways within the heart that cause fast or irregular heart rhythms.
ACE (angiotensin-converting enzyme) inhibitor correct answersA medication that opens up
blood vessels, making it easier for the heart to pump blood forward to the body; also used to
lower blood pressure.
Acyanotic correct answersRefers to a group of congenital heart defects in which there is a
normal amount of oxygen in the bloodstream, giving a pink color to the lips and nail beds.
Anastomosis correct answersA surgical connection, often between two blood vessels.
Aneurysm correct answersA thin, weakened area in a blood vessel or area of the heart.
Angiography correct answersAn x-ray study that uses dye injected into arteries to study blood
circulation.
Angioplasty correct answersA non-surgical procedure for treating narrowed arteries.
Anticoagulant correct answersA medication that keeps blood from clotting.
Antihypertensive correct answersA medication that lowers blood pressure.
Aorta correct answersThe largest artery in the body and the primary blood vessel which carries
oxygenated blood out of the left side of the heart to the rest of the body.
Aortic arch correct answersThe head and neck vessels arise from this part of the aorta, directing
blood from the heart; the remainder of the blood then goes down to the rest of the body.
Aortic regurgitation correct answersBackwards leakage of blood from the aorta, through a
weakened aortic valve, and into the left ventricle, sometimes resulting in stress in the left heart
and inadequate blood flow to the body. It can be trivial, mild, moderate, or severe.
Aortic stenosis correct answersNarrowing of the opening of the aortic valve (the valve that
regulates blood flow from the left ventricle into the aorta). This leads to obstruction of the valve
that can be mild, moderate, severe, or critical.
Aortic valve correct answersThe valve that regulates blood flow from the heart into the aorta.
Apnea correct answersCessation of breathing.
Arrhythmia (Also called dysrhythmia) correct answersA fast, slow, or irregular heartbeat.
Arterioles correct answersSmall branches of arteries.
,Artery correct answersA blood vessel that carries oxygenated blood away from the heart to the
body.
Arteriosclerosis correct answersAlso called atherosclerosis, and commonly called "hardening of
the arteries," a variety of conditions caused by fatty or calcium deposits in the artery walls
causing them to thicken.
Asplenia correct answersAbsence of the spleen, either from improper development before birth,
or due to the surgical removal of the spleen resulting from injury or disease.
Atresia correct answersInadequate development of an organ or part of an organ during
pregnancy.
Atrial fibrillation correct answersA very fast and irregular beating of the atria (the upper two
chambers of the heart).
Atrial flutter correct answersA very fast beating of the atria (the upper two chambers of the
heart).
Atrial septal defect (ASD) correct answersA hole in the wall between the right and left atria (the
two upper chambers of the heart), which can be small, moderate, or large in size.
Atrial septum correct answersThe wall between the right and left atria (the two upper chambers
of the heart).
Atrioventricular canal correct answersRefers to a congenital heart defect involving an opening
low in the atrial septum, an opening high in the ventricular septum, and abnormal development
of the mitral and/or tricuspid valves. Also called atrioventricular septal defect or endocardial
cushion defect.
Atrium (atria plural) correct answersOne of two upper chambers in the heart.
Atrioventricular block correct answersAn interruption of the electrical signal between the atria
and the ventricles.
Atrioventricular (AV) node correct answersA cluster of cells between the atria and ventricles that
regulates the electrical current and is the only normal electrical connection between the atria and
ventricles.
Bacterial endocarditis correct answersA bacterial infection of the valves or interior surfaces of
the heart.
Balloon angioplasty correct answersA procedure usually done in the cardiac catheterization
laboratory that uses a catheter (tube) with a balloon in the tip to open up a narrowed valve or
blood vessel.
, Beta blocker correct answersA medication that limits the activity of epinephrine (a hormone that
increases blood pressure).
Bicuspid correct answersA valve that has two leaflets.
Biopsy correct answersA procedure in which tissue samples are removed from the body for
microscopic examination to establish a diagnosis.
Blood clot correct answersA thick, gelled mass of blood.
Blood pressure correct answersThe force or pressure exerted by the heart when pumping blood;
the pressure of blood in the arteries.
Blood pressure cuff correct answersA device usually placed around the upper portion of the arm
to measure blood pressure.
Brady correct answersPrefix meaning slow.
Bradycardia correct answersAbnormally slow heartbeat.
Bundle-branch block correct answersA condition in which one or more of branches of the heart's
electrical system is unable to normally conduct the electrical signal in the ventricles.
Calcium channel blocker correct answersA medication that lowers blood pressure.
Capillaries correct answersTiny blood vessels between arteries and veins that distribute oxygen-
rich blood to the body.
Cardiac correct answersPertaining to the heart.
Cardiac arrest correct answersThe stopping of heartbeat.
Cardiac catheterization correct answersA diagnostic procedure in which a tiny, hollow tube
(catheter) is inserted into an artery or vein in order to evaluate the heart and blood vessels. The
evaluation includes measuring pressure and oxygen amounts in each chamber as well as
angiography.
Cardiac output correct answersThe amount of blood that goes through the circulatory system in
one minute.
Cardiologist correct answersA physician who specializes in the medical evaluation and treatment
of heart diseases.
Cardiology correct answersThe clinical study and practice of treating the heart.
