Simpson's method of discs

Webb1 nov. 2013 · 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. … Webb6 sep. 2024 · In modified Simpson’s rule, these three sections are assumed to be of equal height. In echocardiography, apical four chamber view and two chamber views are obtained in both systole and diastole. The endocardial borders are traced out. The computer algorithm divides the left ventricular cavity into discs, usually 20 in number.
