E wave deceleration time normal
WebApr 20, 2015 · E wave and e ′ were higher in younger subjects and decreased progressively in the older ones. E / e ′ ratio increased with ageing. Septal e ′ <8 cm/s was present in 19.7% of the subjects in the 40–60 year group and in 55% of those in the ≥60 year group. WebCharacteristic of a restrictive filling pattern include an E/A ratio more than 2.5, a mitral inflow E wave deceleration time less than 150 msec, and decreased tissue Doppler velocities when interrogating the lateral and septal mitral annulus (<5 cm/sec). E/e′ ratios are often more than 14 and there is marked biatrial dilatation. 4.
