A Computer Simulation Study of Anatomy Induced Drift of Spiral Waves in the Human Atrium

Figure 5

Cross-sectional endocardial views of the atrial geometry. (a) Overall anatomical structures considered in this study that give varying wall thickness, ridges, or bridge formations. The dotted line shows where a further cross section was taken and the arrow indicates the view of panel (b). A red dot is placed which indicates the orientation of panel (b) with respect to this panel. (b) The PM bridge in the 3D anatomical model which joins the atrial wall only at junctions J1 and J2.
