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 ... 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 ...
