Cardiovascular system Diseases and Conditions Flashcards
Surgical procedure that opens a blocked artery by inflating a small balloon within a catheter to widen and restore blood flow in the artery
angioplasty
ĂN-jē-ō-plăs-tē
angi/o: vessel (usually blood or lymph)
-plasty: surgical repair
Art gets carried away with oxygenated blood!
Large blood vessels that carry oxygenated blood away from the heart
arteries
Microscopic blood vessels joining arterioles and venules
capillaries
Pertaining to presence of a disorder at the time of birth, which may result from genetic or environmental causes
congenital
Sum of all physical and chemical changes that take place within an organism
metabolism
Vessels that return deoxygenated blood to the heart
veins
Irregularity or loss of rhythm of the heartbeat; also called dysrhythmia
arrythmia
ă-RĬTH-mē-ă a-: without, not
rrhythm: rhythm -ia: condition
Arrhythmia in which there is rapid, uncoordinated quivering of the myocardium that can affect the atria or ventricles; usually described by the part that is contracting abnormally
Fibrillation
Thickening, hardening, and loss of elasticity of arterial walls; also called hardening of the arteries
arteriosclerosis
scler-hardeing
osis-abnomal condition
Healthy arteries are flexible and elastic. But over time, the walls in t
Most common form of arteriosclerosis caused by accumulation of fatty substances within the arterial walls, resulting in partial and, eventually, total blockage
atherosclerosis
Soft blowing sound heard on auscultation caused by turbulent blood flow
auscultation-listening to the body with a stethescope

bruit
brwe
Mass of undissolved matter (commonly a blood clot, fatty plaque, or air bubble) that travels through the bloodstream and becomes lodged in a blood vessel
embolus
us-condition
embol- plug
Disease of the electrical system of the heart, which controls activity of heart muscle
heart block
Atrioventricular (AV) block in which atrial electrical impulses are delayed by a fraction of a second before being conducted to the
first-degree
AV block in which only some atrial electrical impulses are conducted to the ventricles
second-degree
AV block in which no electrical impulses reach the ventricles; also called complete heart block (CHB)
third-degree
complete heart block
CHC
Occurs when the heart is unable to pump enough blood flow to meet the needs of the body and can cause a number of symptoms, such as shortness of breath, leg swelling, and exercise intolerance
Heart Failure
HF
Consistently elevated blood pressure, causing damage to the blood vessels and, ultimately, the heart
Hypertension
HTN
tension-stress
hyper-excessive, above normal
Inadequate supply of oxygenated blood to a body part as a result of an interruption of blood flow
ischemia
emia-blood
