When 2D measurements are used, the wall thicknesses and linear dimensions should be measured at the level of the LV minor dimension, at the mitral leaflet tips level. The upper limit of normal for LVDd is smaller than the M-mode measurement. Left ventricle internal dimension diastole (LVIDd), inter-ventricular septum diastole (IVSd), and posterior wall diastole (PWd) are measured at end-diastole from 2D or M-mode recordings, preferably on several beats.

Após tantos anos, as medidas do VE ainda geram confusão .
Ligar o ECG para fazer no 2D é obrigatório.
Usar uma tabela de normalidade feita em 2D é questão de bom senso.
