cardiovascular 2; heart layers Flashcards
asymptomatic
flu-like or death
resolves itself in 2 months from virus
myocarditis
korotkoff sounds
used to measure blood pressure
pericardial effusion examples
tamponade
pulsus paradoxus
AV =
aortic valve
pericardial effusion
accumulation of fluid in pericardial cavity
when fluid is in a sack or cavity
effusion
aortic valve stenosis
asymptomatic until less than 25%
exaggerated decrease in systolic blood pressure; blood cant get all over body
pulsus paradoxus
pericardium
double-layered serous membrane
asympatomatic until less than 25%
aortic valve stenosis
pericarditis
triad of symptoms
dyspnea
tachycardia
flu-like symptoms
english for swelling
distend
double-layered serous membrane
pericardium
if left ventricle is affected by pericardial effusion
decreased cardiac output
decrease bp; shock
distend
swelling
aortic valve regurgitation
blood flows backwards into left ventricle; fine co until late (korotkoff sounds 0)
mitral valve =
bicuspid valve
if right ventricle is affected by pericardial effusion
increase venous pressure; jugular distension
blood has backed up into the lungs
blood in mucus wet cough
stenosis
parietal layer
outside layer
layer that covers heart
visceral
left atria distends with left ventricle impaired filling
mitral valve stenosis
tamponade
increase pressure from fluid in pericardial sac; decrease cardiac output
diuretics needed
mitral valve regurgitation
stroke volume is divided between aorta and blood falls back into left atria
triad of symptoms
chest pain
friction rub
EKG changes
outside layer of heart
parietal layer
blood flows backwards into left ventricle; fine co until late (korotkoff sounds 0)
aortic valve regurgitation
pericarditis
inflammation of pericardium
valves get infected and get thicker, opening is smaller; potential clots
stenosis
triad of symptoms
chest pain
friction rub
EKG changes
increased pressure from fluid in pericardial sac; dec cardiac output
tamponade
MV =
mitral valve
triad of symptoms
dyspnea
tachycardia
flu-like symptoms
acute pericarditis
effusion
when fluid is in a sack or cavity
inflammation in heart can only happen here
valves
regurgitant
allowing backflow
stroke volume is divided between aorta and blood falls back into left atria
mitral valve regurgitation
infective endocarditis
bacterial infection of heart valves
pulsus paradoxus
exaggerated decrease in systolic blood pressure; blood cant get all over body
diuretics needed
allowing backflow
regurgitant
myocarditis
inflammation of the heart muscle
stenosis
valves get infected and get thicker, opening is smaller; potential clots
wet cough from blood in lungs
mitral valve stenosis
left atria distends with left ventricle impaired filling
bicuspid valve =
mitral valve
visceral layer
covers heart
myocarditis traits
asymptomatic
flu-like or death
resolves itself in 2 months from virus
chest pain
friction rub
EKG changes
triad of symptoms
