Mechanical Deformation of Myocardial Tissue with Cellular Automaton

doi:10.19596/j.cnki.1001-246x.7659

Abstract

Abstract: Effect of mechanical deformation on spiral waves in myocardial tissue is studied with Greenberg-Hastings cellular automaton. It shows that for stable spiral waves existing in a regular lattices system, physiological deformation leads to meandering but not breakup of spiral waves. However, pathological deformation results in breakup, meandering, or disappearance of spiral waves. Simulation results show that spiral waves are more sensitive to amplitude than to angular frequency of mechanical deformation. The quick recovery of a sportsman after hitting on breast and fibrillation coming from violent hitting on breast was explained.

Key words: cellular automata, mechanical deformation, spiral wave, spiral turbulence
