Spiral and scrollwave dynamics in an excitable medium and their behaviour around excitation patterns and heterogeneities

Abstract

Spiral and scroll wave activity in chemical systems is a growing area of research, especially due to their close link with complex biological processes. The propagation of these waves in the heart tissue gives rise to arrhythmias, some of which can be life threatening. Their effective treatment requires the complete knowledge of these waveforms and their possible control. The Belousov-Zhabotinsky (BZ) reaction, an oscillatory, red-ox reaction, is widely used as a laboratory model for these studi newline
