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

Figure 1

2D simulation of AF with stationary reentry. (a) Spiral wave reentry (left) with spiral wave tip trace (right). The diameter of the spiral wave core (8 mm) is indicated in the right hand side panel. (b) Analysis of representative AP profile (top panel) from the 2D simulation. PSD of the representative AP profile (bottom left) showing a peak frequency of around 9.2 Hz. Recurrence map (bottom right) of consecutive cycle length durations of AP profile indicates the monomorphic nature of the reentry.
