WebJul 19, 2024 · S/D ratio, RI and PI are the three best known indices to describe arterial flow velocity waveforms. All three are highly correlated. RI and S/D ratio estimate the relationship between PSV and EDV in the Doppler waveform (RI = (S − D)/S, S/D ratio = S/D, where S is peak systolic velocity and D is end-diastolic velocity). Webo Peak TR velocity > 2.8 m /sec Diastolic function is normal if more than half of the available variables are normal (<50% positive) ... PVs:PVd velocity ratio or VTI ratio < …

Tissue Doppler echocardiography (TDE) is used in the assessment of diastolic function, however, it is unclear whether the medial ( E ′ med) or lateral ( E ′ lat) annulus should be used. Our aim was to compare the diagnostic utility of E ′ med and E ′ lat.
