Representation of the local coordinate system employed by a LDRBM for an idealized ventricular domain. Only directions on the endocardium \(\Gamma _\text{endo}\) are represented. In blue: unit transmural direction, \(\widehat{\varvec{e}}_t\). In green: unit normal direction, \(\widehat{\varvec{e}}_n\). In red: unit longitudinal direction, \(\widehat{\varvec{e}}_l\). Right: zoom on a slab of the left ventricular myocardium showing the three final myofibers orientations \({\varvec{f}}\), \({\varvec{s}}\) and \({\varvec{n}}\)
