摘要

利用改进的FitzHugh-Nagumo系统的有限元解模拟了在三维空间曲面上传播的可重入螺旋波。在某些条件下，即使在不存在非均质性或各向异性的情况下，表面拓扑结构也会引起名义上静止的螺旋的漂移。这些动态可能是重要的维持再入性心律失常。

Stability of spiral wave reentry on curved surfaces

Reentrant spiral waves propagating on curved surfaces lying in 3D space were modeled using a finite element solution of a modified FitzHugh-Nagumo system. Under some conditions, surface topology could induce drift of nominally stationary spirals, even in the absence of heterogeneity or anisotropy. These dynamics may be important in the maintenance of reentrant arrhythmias.
