Simpson's method echo
http://www.tnecho.com/view/45/simpsons-ejection-fraction 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.
