Table 2 Diastolic flow and strain rate indices. (SD in parentheses)

From: Flow propagation velocity is not a simple index of diastolic function in early filling. A comparative study of early diastolic strain rate and strain rate propagation, flow and flow propagation in normal and reduced diastolic function

  1. E: Peak mitral flow velocity in early diastole. Dec-t: deceleration time of early transmitral flow. IVR: isovolumic relaxation time. E/A: ratio of early and late peak mitral flow. PVFe: Flow propagation velocity. Ea: Peak annulus velocity during early filling. SRe: Peak strain rate of early filling phase. PVSe: Strain rate propagation velocity.
