Wilson Ch 66 Flashcards
Angina
A condition marked by spasmodic suffocative attacks
Aneurysm
Sac formed by the localized dilation of the wall of an artery, vein, or heart
Angina pectoris
Acute pain in the chest from decreases blood supply to the heart muscle
Anoxia
Absence of oxygen in the tissues; may be accompanied by deep respirations, cyanosis, increased pulse rate, and impairment of coordination
Anticoagulant
A substance that suppresses, delays, or nullifies coagulation of the blood
Apnea
Temporary cessation of breathing
Arrhythmia
Variation from the normal rhythm, especially with reference to the heart
Arterial blood
Oxygenated blood carried by an artery away from the heart to nourish the body tissues
Asphyxia
A condition in which there is a deficiency of oxygen in the blood and an increase in carbon dioxide
Atheroma
Lipid (cholesterol) deposit on the intima (lining) of an artery, also called atheromatous plaque
Bradycardia
Slowness of heartbeat with slowing pulse rate to less than 60 per minute
Cyanosis
Bluish discoloration of the skin and mucous membranes cause by excess concentration of reduced hemoglobin in the blood
Diaphorosis
Profuse perspiration
Dyspnea
Labored or heavy breathing
Echo cardiology
Recording the position and motion of the heart walls and internal structures of the heart and neighboring tissue by the echo obtained from beams if ultrasonic waves directed through the chest wall
Edema
Abnormal accumulation of fluid in the intercellular spaces if the body
Electrocardiography
The graphic recording from the body surface of the potential of electric currents generated by the heart as a means on studying the action of the heart muscle
Embolism
The sudden blocking of an artery by a clot of foreign material, an embolus, that has been brought to its site of lodgment by the bloodstream; may be a blood clot (most frequently) or an air bubble, a clump of bacteria or a fat globule
Heparin
Anticoagulant, prevents platelet agglutination and thrombus formation
Hypoxia
Diminished availability of oxygen to blood tissues
Infarct
Localized area of ischemic necrosis produced by occlusion if the arterial supply or venous drainage of the part
Ischemia
Deficiency of blood to supply oxygen in part resulting from functional constriction or actual obstruction of a blood vessel
Lumen
The cavity or channel within a tube or tubular organ, such as a blood vessel or the intestine
Murmur
Irregularity of heartbeat caused by a turbulent flow of blood through a valve that has failed to close
Myocardium
The middle and thickest layer of the heart wall; composed of cardiac muscle
Occlusion
Blockage, state of being closed
Prolapse
Downward displacement
Restenosis
Recurrent stenosis
Sclerosis
Induration, hardening
Arteriosclerosis
Group of diseases characterized by thickening and loss of elasticity of the arterial wall
Shunt
Abnormal communication between chambers or blood vessels
Verb: to bypass, divert
Stenosis
Narrowing or contraction of a body passage or opening
Tachycardia
Abnormally rapid heart rate, usually over 100 beats per minute
Tetralogy
A group or series of four
Tetralogy of Fallot
Congenital cyanotic malformation of the heart that includes pulmonary stenosis, ventricular septal defect, hypertrophy of the right ventricle, and dextroposition of the aorta
Thrombus
Blood clot attached to the intima I a loos vessel; may occlude the lumen; contrast with embolus, which is detached and caries by bloodstream
Venous blood
Non oxygenated blood from the tissues; blood pumped from the heart to the lungs for oxygenation
