How to Explain Why 'Unequal Anisotropy Ratios' is Important Using Pictures but No Mathematics

摘要

"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, author explains the role of unequal anisotropy ratios using pictures rather than mathematics. The goal is to develop physical insight, so has to understand qualitatively why the condition of unequal anisotropy ratios is so important
