Visceral Pericardium or Epicardium
the inner layer of the pericardium that hugs the heart is called which two names
valve disorder where valves leak allowing some blood to flow backward into the chamber from which it came
Rheumatic Heart Disease
streptococcal infection, when strep throat isn't treated or antibiotic is not finished this can occur
severe chest pain caused by inadequate oxygen to the heart, lasts 15-30 min, will resolve with rest or nitroglycerin
the pacemaker, located in wall of right atrium near opening of superior vena cava; SA
condition in which cardiac muscle fibers are out of step, producing no effective pumping action; quivers like jello
Congestive Heart Failure
inability of the left ventricle to pump effectively, resulting in congestion of the systemic and pulmonary circulations
carry blood from the arterioles to the venules, smallest blood vessel in the body, only one layer
with arteries it's the smooth inner layer of the blood vessels that consists of endothelial cells
reduces flow of blood, possibly causing ischemia that may progress to necrosis (gangrene)
type of arteriosclerosis caused by lipids; lipids build up on inside wall of blood vessels and can partially or totally block blood flow
enlarged veins in which blood pools because the valves are not working right, usually in the lower legs
phlebitis accompanied by thrombus formation; may result in fatal pulmonary embolism
Strength of Heart Contractions
affect cardiac output, stronger heartbeart increases pressure, weaker beat decreases it
less than normal viscosity decreases pressure, more than normal viscosity increases pressure
drop in blood volume that causes blood pressure and blood flow to drop, also can be caused by loss on interstitial fluid due to blood loss
caused by nerve condition that dilates blood vessels and thus reduces blood flow; loss of sympathetic impulses sent to smooth muscles of blood vessels
SA Node, AV Node, Bundle of HIS, Bundle Branches, Purkinje Fibers
electrical conduction pathway, 5 of them...
may be viral, bacterial or fungal infection, may be result of systemic disease, inflammation of the myocardium
