valvular disease Flashcards
passive leg raise increases ____
preload
squatting increases ____
preload (because when you squat, vasoconstrict and shunt blood back to heart)
decrease preload- which manuevers
valsalva (straining) inspiration (increase the preload on RV)
standing (moving blood down from the legs)
expiration effect on preload
decrease the RV preload
right sided murmur what intensifies
inspiration
expiration increases intensity of
left sided murmur
What increases afterload (manuever)
increased hand grip
squatting
because it increases SVR
diastolic murmurs are almost always
abnormal
classic triad of aortic stenosis
SAD: syncope, angina, dyspnea
pulsus parvus et tardus- what does it mean
seen in aortic stenosis. weak and late pulse. longer, because it takes a long time to get the high pressure out of the aorta.
A2P2- seen in
aortic stenosis
harsh crescendo decresendo systolic ejection murmur- radiates to carotids: which murmur
aortic stenosis
location of aortic stenosis
R 2ND ICS
Cause of aortic stenosis (3)
dystrophic calcification (normal levels of calcium) but high deposition of calcium on aortic valve esp in elderly patients
bicuspid aortic valve- fusion of aortic leaflets in young patients
rhuematic fever
aortic regurgitation
regurg blood back into the left ventricle
can be acute or chronic
