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].
