Diastology Flashcards
Normal E/A ratio
Between 1-2
Deceleration time in normal diastolic function
130-230
E/E’ in normal diastolic function
Less than 8
E/A ratio in Grade 1
Less than 1
S/D in normal diastolic function
More than 1 (systolic is bigger)
E/E’ in Grade 1
Less than 8
S/D in Grade 1
More than 1 (systolic is bigger)
Deceleration time in Grade 1
More than 230
Deceleration time in Grade 2
130-230
E/A in Grade 2
Between 1-2
S/D in Grade 2
Less than 1, diastolic is bigger
E/e’ in grade 2
Usually more than 13
E/A in Grade 3
> 2
Deceleration time in Grade 3
Less than 130
E/e’ in Grade 3
More than 13
S/D in Grade 3
<1, diastolic is bigger
Normal IVRT
50-100
Grade 1 IVRT
> 100

What is an a wave in pulmonary venous flow
represents flow reversal in pulmonary vein during atial systole
When wouldnt you see an a wave in pulmonary venous flow
if pt isnt in sinus rhythm
Peak atrial reversal velocity (PVa) in normal diastolic function
<0.35 m/s
Peak atrial reversal velocity (PVa) in grade 1 diastolic dysfunction
<0.35 m/s
Peak atrial reversal velocity (PVa) in grade 2 diastolic dysfunction
> 0.35 m/s
Peak atrial reversal velocity (PVa) in grade 3 diastolic dysfunction
> 0.35 m/s
Duration of atrial reversal (adur) - Duration of A wave measured on LV inflow (adur) in normal diastolic function
<20ms
Duration of atrial reversal (adur) - Duration of A wave measured on LV inflow (adur) in grade 1 diastolic dysfunction
<20ms
Duration of atrial reversal (adur) - Duration of A wave measured on LV inflow (adur) in grade 2 diastolic dysfunction
> 20ms
Duration of atrial reversal (adur) - Duration of A wave measured on LV inflow (adur) in grade 3 diastolic dysfunction
> 20ms
