Also called a total artificial heart (TAH).Īscending aorta – The first portion of the aorta, emerging from the heart’s left ventricle.Īspirin – Acetylsalicylic acid a medicine used to relieve pain, reduce inflammation, and prevent blood clots.Ītherectomy – A nonsurgical technique for treating diseased arteries with a rotating device that cuts or shaves away material that is blocking or narrowing an artery.Ītherosclerosis – A disease process that leads to the buildup of a waxy substance, called plaque, inside blood vessels.Ītrium (right and left) – The two upper or holding chambers of the heart (together referred to as atria).Ītrial flutter – A type of arrhythmia in which the upper chambers of the heart (the atria) beat very fast, causing the walls of the lower chambers (the ventricles) to beat inefficiently as well.Ītrial septal defect – See septal defect.Ītrial tachycardia – A type of arrhythmia that begins in the heart’s upper chambers (the atria) and causes a very fast heart rate of 160 to 200 beats a minute.

When they contract, they raise resistance to blood flow, and blood pressure in the arteries increases.Īrtery – A vessel that carries oxygen-rich blood to the body.Īrteritis – Inflammation of the arteries.Īrteriosclerosis – A disease process, commonly called “hardening of the arteries”, which includes a variety of conditions that cause artery walls to thicken and lose elasticity.Īrtificial heart – A manmade heart. ARVD causes ventricular arrhythmias.Īrteriography – A test that is combined with cardiac catheterization to visualize an artery or the arterial system after injection of a contrast dye.Īrterioles – Small, muscular branches of arteries. It appears to be a genetic condition (passed down through a family’s genes). The test lets doctors measure the blood flow and blood pressure in the heart chambers and see if the coronary arteries are blocked.Īngioplasty – A nonsurgical technique for treating diseased arteries by temporarily inflating a tiny balloon inside an artery.Īngiotensin II receptor blocker – A medicine that lowers blood pressure by blocking the action of angiotensin II, a chemical in the body that causes the blood vessels to tighten (constrict).Īnnulus – The ring around a heart valve where the valve leaflet merges with the heart muscle.Īntiarrhythmics – Medicines used to treat patients who have irregular heart rhythms.Īnticoagulant – Any medicine that keeps blood from clotting a blood thinner.Īntihypertensive – Any medicine or other therapy that lowers blood pressure.Īntiplatelet therapy – Medicines that stop blood cells (called platelets) from sticking together and forming a blood clot.Īorta – The largest artery in the body and the main vessel to supply blood from the heart.Īortic valve – The valve that regulates blood flow from the heart into the aorta.Īphasia – The inability to speak, write, or understand spoken or written language because of brain injury or disease.Īrrhythmia (or dysrhythmia) – An abnormal heartbeat.Īrrhythmogenic right ventricular dysplasia (ARVD) – ARVD is a type of cardiomyopathy with no known cause.

Amiodarone is mainly given to patients who have not responded to other antiarrhythmic medicines.Īneurysm – A sac-like protrusion from a blood vessel or the heart, resulting from a weakening of the vessel wall or heart muscle.Īngina or angina pectoris – Chest pain that occurs when diseased blood vessels restrict blood flow to the heart.Īngiography – An x-ray technique in which dye is injected into the chambers of your heart or the arteries that lead to your heart (the coronary arteries).

It works by regulating nerve impulses in your heart. Ībdominal aorta – The portion of the aorta in the abdomen.ĪCE (angiotensin-converting enzyme) inhibitor – A medicine that lowers blood pressure by interfering with the breakdown of a protein-like substance involved in blood pressure regulation.Īcetylcholine – A type of chemical (called a neurotransmitter) that transmits messages among nerve cells and muscle cells.Īcquired heart disease – Heart disease that arises after birth, usually from infection or through the build-up of fatty deposits in the arteries that feed the heart muscle.Īlveoli – Air sacs in the lungs where oxygen and carbon dioxide are exchanged.Īmiodarone – A kind of medicine (called an antiarrhythmic) used to treat irregular heart rhythms such as atrial fibrillation and ventricular tachycardia. Abdomen – The area of the body between the bottom of the ribs and the top of the thighs.
