Ace Inhibitor
A medicine that lowers blood pressure.
Acquired Heart Disease
Heart disease that develops after birth, usually from infection or build-up in the arteries.
Alveoli
Air sacs in the lungs where oxygen and carbon dioxide are exchanged.
Aneurysm
A sac-like protrusion from a blood vessel or the heart that occurs due to weakening of the vessel wall or heart muscle.
Angina / Angina Pectoris
Chest pain that occurs when diseased blood vessels restrict blood flow to the heart.
Angiography
An x-ray technique in which dye is injected into the chambers of the heart or coronary arteries. Allows doctors to measure the blood flow and pressure in the heart chambers and see if arteries are blocked.
Angioplasty
A nonsurgical technique that treats diseased arteries by inflating a tiny balloon inside the artery.
Annulus
The ring around a heart valve where the valve leaflet merges with the heart muscle.
Antiarrhythmics
Medicines used to treat irregular heart rhythms.
Anticoagulant
Medicines that keep blood from clotting.
AKA: Blood Thinner.
Antihypertensive
Medicines or therapies that lowers blood pressure.
Antiplatelet Therapy
Medicines that stop blood clots.
Arrhythmia
(Dysrhythmia)
An abnormal heartbeat.
Arteriography
A test done during a cath to visualize an artery after injection of contrast dye.
Arterioles
Small, muscular branches of arteries.
Artery
A vessel that carries oxygen-rich blood to the body.
Arteritis
Inflammation of the arteries.
Arteriosclerosis
A disease process causing artery walls to thicken and lose elasticity.
Also called hardening of the arteries.
Atrial Fibrillation
An irregular heartbeat where the atrium in the heart beats rapidly and chaotically.
Atria
The name for both the right and left atrium together.
Arterial Fibrillation (AFIB)
A common condition where the upper chambers of the heart beat irregularly.
Atrial Flutter
A condition in which the upper chambers of the heart beat very fast causing the walls of the lower chambers to beat inefficiently.
Atrial Tachycardia
A condition that begins in the heart’s upper chambers and causes a very fast heart beat of 160 to 200 beats per minute.
Atrioventricular Block
An interruption or disturbance of the electrical signal between the heart’s upper and lower chambers.
Atrioventricular Node
A group of cells between the upper and lower heart chambers that regulates the electrical current that passes to the ventricles.
Bacterial Endocarditis
A bacterial infection of the endocardium or the heart’s valves.
Balloon Valvuloplasty
A procedure to repair a heart valve by inflating a balloon to open and separate valve leaflets.
Beta Blocker
A medicine that lowers blood pressure by limiting the activity of epinephrine.
Blood Clot
A jelly like mass of blood tissue that stops the flow of blood.
Blood Pressure
The force or pressure exerted by the heart in pumping blood.
Bradycardia
Abnormally slow heartbeat.
Bruit (Broot)
The sound made in the blood vessels resulting from turbulence due to plaque buildup or damage.
Bundle Branches
2 pathways that carry electrical impulses from the AV node to the left and right ventricles.
Bundle Branch Block
A condition in which part of the heart’s conduction system is defective and unable to conduct the electrical signal normally, causing an irregular heartbeat.
