title: How to explain why "unequal anisotropy ratios" is important using pictures but no mathematics.
abstract: "Unequal anisotropy ratios" is an important property of cardiac tissue. Many of the fundamental mechanisms governing how the heart responds to an electrical shock require unequal anisotropy ratios. In this paper, I explain the role of unequal anisotropy ratios using pictures rather than mathematics. My goal is to develop physical insight, so has to understand qualitatively why the condition of unequal anisotropy ratios is so important.
