Webb28 feb. 2024 · Background . Left ventricular ejection fraction (LVEF) and end diastolic volume (EDV) are measured using Simpson’s biplane (SB), 3-dimensional method (3DE), and speckle tracking (STE). Comparisons between methods in routine practice are limited. Our purpose was to compare and to determine the correlations between these three … Webb7 apr. 2013 · Methods: Simpson’s method of discs-derived EDV and ESV were measured using offline analysis by 1 observer, in both the right parasternal and the left apical views. Measurements were compared between both views and between male and female dogs using a t-test. Reference intervals were established using the mean + 2 9 SD.

Webb6 sep. 2024 · Basic assumption in Simpson’s rule is that the shape of the left ventricular cavity is a composite of a cylinder (from base to the level of the mitral valve), a truncated cone from mitral valve level to the level of the papillary muscles and a cone from there to the apex [1]. Volume of the cylinder: A m x L/3. Volume of the truncated cone ...
