sinus rhythm
normal heart rate
ventricle
lower pumping chamber of the heart
infarct
area of damaged tissue due to lack of blood supply
flutter
rapid, coordinated heart beat
coronary sinus
collects venous blood from the heart and empties it into the right atrium
sinoatrial node
group of cells in the right atrium that initiates the heart beat
heart rate
beats per minute
cardiac cycle
sequence of heart relaxation and contraction
fibrillation
rap, UNcoordinated heartbeat
tricuspid valve
right atrioventricular valve
LDL
bad cholesterol, carries cholesterol from liver to tissues
extrasystole
extra beat of the heart
tachycardia
more than 100 bpm
bradycardia
less than 60 bpm
cardiac output
volume of blood pumped in one minute
heart failure
inability to pump blood, myocardium becomes week and stiff
occlusionq
closing of a vessel
ventricular septal defect
congenital disease where there is a hole in the interventricular septum
patent ductus arteriosis
persistence of the ductus arterioles after birth
myocardial infarction
tissue damage usually due to a heart attack
coarctation of the aorta
narrowing of the aortic arch
endocarditis
