Unpinning of a spiral wave anchored around a circular obstacle by an external wave train: Common aspects of a chemical reaction and cardiomyocyte tissueEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Masanobu Tanaka, Akihiro Isomura, Marcel Horning, Hiroyuki Kitahata, Konstantin Agladze et al. It is well known that spiral waves are often stabilized by anchoring to a local heterogeneity (pinning) and that such pinned waves are rather difficult to eliminate. In the present report, we show that pinned spiral waves can be eliminated through collision with a wave train arriving from the outer ... [Chaos 19, 043114 (2009)] published Thu Nov 19, 2009.
