Soling Zimik, Rupamanjari Majumder, Rahul Pandit

摘要:

心脏组织的电特性的空间变化可由于心脏疾病而发生。我们引入这样的梯度到心脏组织的数学模型,然后研究,通过广泛的数值模拟,他们的影响折返电波和他们的稳定性在两个和三个维度。我们解释了螺旋和涡旋波的不稳定性,这需要各向异性变薄的波的波长,因为在其电气性能的各向异性变化的机制。

英文摘要:

Spatial variations in the electrical properties of cardiac tissue can occur because of cardiac diseases. We introduce such gradients into mathematical models for cardiac tissue and then study, by extensive numerical simulations, their effects on reentrant electrical waves and their stability in both two and three dimensions. We explain the mechanism of spiral- and scroll-wave instability, which entails anisotropic thinning in the wavelength of the waves because of anisotropic variation in its electrical properties.
