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

Figure 3

Summary of the anatomical model simulations. Column (a) shows data for clockwise and column (b) shows data for anticlockwise SW simulations. Top row shows nine selected tip traces of the spontaneously drifting scroll waves in different colours. On each trace, the red dot is the earliest point and the black dot is the latest point of the tip trace. The traces are also enumerated, and the numbers are referred to in the text. The initiation location of traces with the same numeric labelling is the same in the left and right panels. Bottom row shows typical snapshots of spiral waves seen on the surface nearest to the viewer. Left panel shows a clockwise rotating spiral while the right panel anticlockwise rotating spirals. The cross in the top right (left panel) designates the position of the registration electrode where a representative AP was recorded.
