diastolic dysfunction shorten Flashcards
(28 cards)
what is diastolic dysfunction ?
problem w/ diastole
Diastolic dysfunction occurs
lower chamber don’t relax properly
Diastolic dysfunction leads to ….
diastolic HF
Diastolic dysfunction best viewed > ….
apical 4 chamber
E Wave or AKA …..
Early diastolic filling
In E Wave, MV are … & blood >
open / passively filling
A Wave or AKA ….
atrial contraction phase
In A Wave, Lt atrial pressure ……
increase
LT ………> …… than LT …….
ventricle / higher / atrium
In A Wave, MV > ….
closed
normal E/A ratio
E velocity > greater than A velocity
normal range : E/A ratio
0.75-1.5
In older age …… wave >
E / smaller ( hypertrophy)
In E/A ratio, ……. becomes …… & causes
Lt vent / stiff slowing down E wave / reduced E/A ratio
tissue doppler index
2nd component used > assess diastolic dysfunction
TDI measures
velocity : myocardium through cardiac cycle
how do we get TDI ? USE …..
PW > medial / lateral annulus
TDI gives us
E ( E prime) & A ( A prime)
In normal diastolic dysfunction …
… Wave …. than … Wave
E/A ratio =
TDI =
E / Greater / A
0.75 - 1.5
E greater than A
Impaired relaxation is what grade of DD
1
what is the name : grade 1 DD
Impaired relaxation
Grade 1 : Impaired relaxation
… Wave = … velocity than … wave
….. E/A ratio =
TDI =
E / lower / A
reduced / < 1
E less than A
Pseudonormal is grade what : DD
2
what is the name : grade 2 DD
Pseudonormal
