Unconventional Collective Resonance as Nonlinear Mechanism of Ectopic Activity in Excitable Media

Autor: Teplenin, Alexander S., Kudryashova, Nina N., Majumder, Rupamanjari, de Vries, Antoine A. F., Panfilov, Alexander V., Pijnappels, Daniel A.

Many physical, chemical and biological processes rely on intrinsic oscillations to employ resonance responses to external stimuli of certain frequency. Such resonance phenomena in biological systems are typically explained by one of two mechanisms: e

The generation of abnormal excitations in pathological regions of the heart is a main trigger for lethal cardiac arrhythmias. Such abnormal excitations, also called ectopic activity, often arise from areas with local tissue heterogeneity or damage ac
