WebbThe ejection volume divided by the end-diastolic volume is the ejection fraction. The formula used is the Tiecholz formula which is based upon the spherical volume of the heart multiplied by a correction factor. Since the volume of a sphere is the cube of the radius, and the left ventricle is almost a sphere, a correction factor to account for ... 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.

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 … flying knee kick
