  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.
