                 excitation wave over the atria following initiation in a
                 given focus in an atrial model containing its overall
                 geometry only, i.e., without atrial bundles. METHODS AND
                 RESULTS: The propagation velocity of the excitation wave
                 was taken to be uniform, and the wall thickness was
                 discarded. The timing of excitation of any point on the
                 atrium thus becomes directly proportional to its shortest
                 distance over the atrial wall to the focus. Despite these
                 gross simplifications, the general nature of the
                 excitation sequence found corresponded closely to clinical
                 data reported in the literature. This suggests that the
                 complex overall geometry of the atria dominates the timing
                 of the excitation. A highly intriguing observation from
                 this study was that, when looking at the pathways from the
                 sinus node to all other points on the atrium, prominent
                 routes became visible even though no such pathways formed
                 part of the model of the atrial geometry used. The
                 locations of these prominent routes coincide with those of
                 various distinct bundles in the atria. Possible inferences
                 of these observations are discussed. CONCLUSION: Based
                 upon comparison with data from other studies, it is
                 concluded that, during stable heart rhythms, propagation
                 of the atrial excitation wave is well approximated by an
                 assumption of uniform velocity, even though no atrial
                 bundles were included in the model. The overall geometry
                 seems to be the dominant factor in the spread of
                 excitation.",
