Ch. 7 Cardiology Flashcards
Arrhythmia
irregular heart beat
cardiopulmonary
pertaining to heart and lungs
ischemia
loss of blood supply
fibrillation
abnormal quivering of heart
hypertension
high blood pressure
bradycardia
abnormally slow heart beat
cardiospasm
involuntary heart muscle spasm
coronary
pertaining to the heart
arteriosclerosis
hardening of an artery
pacemaker
electrical device to stimulate the heart beat
Cardiovascular system consists of…
heart & blood vessels
What are the three types of blood vessels?
Arteries, veins, & capillaries
Arteries
carry blood away from heart
veins
carry blood toward heart
capillaries
oxygen and nutrients are delivered here/carbon dioxide and wastes are picked up
cardiovascular technologists
perform variety of procedures:
electrocardiography, echocardiography, cardiac catheterization
what are the reasons why plaque forms in the coronary artery?
behavior/diet
embolus
blood clot
where is a pacemaker placed?
under the skin between the heart and shoulder; electrode wires the run to the heart muscle
What are the steps of placing a stent in a blood vessel?
(A) Catheter is used to
place a collapsed stent next to an atherosclerotic plaque; (B) stent is expanded; (C)
catheter is removed, leaving the expanded stent behind
how do varicose veins develop?
valves fail to control blood flow, which allows more than the normal amount of blood to collect in superficial leg veins
