-
blood is forced OUT of the heart
systole (strongest)
-
blood fills the ventricles
diastole (weakest)
-
these collect blood
atria
-
these pump blood out from the heart
ventricles
-
right side pump deals with the
lungs
-
left side pump deals with the
rest of the body besides the lungs
-
-
the atria contract when (nodes)
SA to AV node
-
the ventricles contract when
His to Purkinje
-
which wave is depolarization, contraction of atria?
P wave
-
which wave is contraction of ventricles, depolarization?
QRS
-
which wave is recovery (repolarization)?
T wave
-

-
aneurysm/o **
widening, widened blood vessel
-
-
-
-
-
-
-
blood clot that obstructs a vessel
thrombus
-
when a thrombus travels through the vessels it is called
an embolus
-
removal of innermost wall of artery
endarterectomy
-
any dz that interferes with the ability of coronary arteries to deliver sufficient blood to the myocardium
coronary artery disease
-
area of tissue that undergoes necrosis after cessation of blood supply
infarct
-
-
balloon acronym
PTCA: percutaneous transluminal coronary angioplasty
-
CABG
coronary artery bypass graft (uses vein)
-
small masses of fibrin and platelets from bax lodging in weakened heart tissue
vegetations
-
enlarged, twisted superficial veins
varicose veins
-
when vein valves aren't working you get
varicose veins
-
another word for "not working" (like vein valves in varicose veins)
incompetent
-
soft blowing sound/murmur
bruit
-
coarctation
narrowing of a vessel (aorta)
-
quivering/spontanous muscle contrax causing ineffectual contrax
fibrilliation
-
palpitation
sense that heart is not beating normally (can include many)
-
when blood from the aorta goes into the pulmonary artery (because it didn't close at birth)
patent ductus arteriosis
-
circulation of blood through tissues
or
passage of fluids through vessels of an organ
perfusion
-
reduction of the LUMEN caused by smooth muscle contraction
vasoconstriction
-
widening of the LUMEN caused by smooth muscle relaxation
vasodilation
-
blood flows (slowly, quickly) through capillaries
slowly--gives it time to make the gas exchange
-
hardened plaque
atherosclerosis
-
bulge that might rupture
aneurysm
-
hollow thin mesh tube placed in artery after angioplasty to keep it open
stent
-
ischemia
oxygen deprivation
-
troponin T
troponin I
creatinine kinase
these three are
cardiac enzymes
-
how do cardiac enzymes help dx MI?
they do predictable things at certain intervals after MI.
-
endocarditis can be ____ or _____
infective (microbes) or noninfective (thrombi).
-
backflow of blood (through a valve when there shouldn't be)
regurgitation
-
small masses of fibrin and platelets in weakened heart tissue (because of bax)
vegetations
-
vegetations collect on the valves, causing
backflow, regurgitation
-
what happens in varicose veins?
valves are incompetent, allows backflow, bulge
-
primary tumor of the heart
myxoma (mucous connective tissue)
