(a) Schematic representation of the method used to replicate the BDM model wavefront shape and conduction velocity using the MDMEQ approach within the complex whole ventricular geometry, using the same method as shown in Fig. 1(b). Here, a longitudinal slice through the ventricles is shown with the two tissue elements immediately bordering the tissue edges at the tissue-bath interface (corresponding nodes shown in blue) tagged and assigned increased conductivity values, scaled by R^ζ in the respective conductivity direction (ζ = l, t). (b) Simulation results following apical pacing within the whole-ventricular rabbit model using BDMNB, BDM and MDMEQ approaches. Top row shows snap-shots of V_m distribution throughout the ventricular cavities, where clipping planes have been used to facilitate visualisation of the activity within the cavities. Bottom row shows activation time maps (in ms) from the onset of the pacing stimulus until the time of first activation of each myocardial node point.
