We studied 72 healthy subjects; 31 of them were adults and 41 children. By means of two-dimensional echocardiography we obtained a short axis view at the papillary muscle level of the ratio of the thickness (h) of the ventricular wall and the radius (r) of the cavity. We analysed ventricular performance determinants (pre-load, after-load and contractility). This non-invasive method gives information similar to pressure-volume curves. Thus, we propose it for the study of left ventricular overloads.
