Simpson's method of discs

Webbechocardiography methods are most often used for the assessment of ventricular function in veterinary medicine – Teicholz and modified Simpson‘s method of discs (SMOD). Teicholz method uses M-mode echocardiographic measurements for calculation of left ventricular volumes and cardiac output. Webb1 nov. 2013 · The Teichholz method for calculation of LV volumes results in inaccuracies as a result of the geometric assumptions required to convert a linear measurement to a three‐dimensional (3D) volume.7, 8 According to the American Society of Echocardiography (ASE), the current recommendation for two‐dimensional (2D) volume …
