Simpson's method echo
WebbThe Simpson method is also known as the method of discs because it integrates volume by fitting numerous discs into the ventricle and sums up their volume. The volume of each disc is determined by the diameter of the disc and its height. Simpson Volume = (A1 + A2 +...+An) x h The measurement is performed the same way as the area length method.

The group with left ventricular hypertrophy differed from the normal controls with respect to wall thickness (p < 0.001), heart rate (p = 0.006), mitral ring motion (p < 0.001), and the ratio of mitral ring motion to short axis diameter (p < 0.001); there …
Webb8 sep. 2014 · Inter-method repeatability was calculated by intra-class correlation coefficients (ICC) and agreement evaluated by Bland Altman plots. Results All measurements were obtained in all cases and showed ICC for left ejection fraction of 0.90 (95% confidence interval (95% CI) 0.78-0.95) and ICC of 0.90 (95% CI 0.80-0.96) for right … WebbEvaluation of the Simpson's Method to Determine Left Ventricular Ejection Fraction Using the Transgastric Two-Chamber View This study suggests the Simpson's method can be …
WebbSimpson's method of disc measurements were performed on left parasternal apical 4-chamber view and using the right parasternal long-axis view. Left ventricular area was measured by tracing the endocardial border in end-systole and end-diastole and maximal LV length was measured from the mitral annulus to the endocardial border of the LV apex.
