Unconventional Collective Resonance as Nonlinear Mechanism of Ectopic Activity in Excitable Media
Alexander S. Teplenin, Nina N. Kudryashova, Rupamanjari Majumder +3
Many physical, chemical and biological processes rely on intrinsic oscillations to employ resonance responses to external stimuli of certain frequency. Such resonance phenomena in…
Cardiac Mechano-Electrical Dynamical Instability
L. D. Weise, A. V. Panfilov
In a computational study we reveal a novel dynamical instability of excitation waves in the heartmuscle. The instability manifests itself as gradual local increase in the duration…
The statistical properties of spiral- and scroll-wave turbulence in cardiac tissue
K. V. Rajany, Anupam Gupta, Alexander V. Panfilov +1
Disorganized electrical activity in the heart leads to sudden cardiac death. To what extent can this electrical turbulence be viewed as classical fluid turbulence,which is an impor…
Scroll-wave dynamics in the presence of ionic and conduction inhomogeneities in an anatomically realistic mathematical model for the pig heart
R. Majumder, R Pandit, A. V. Panfilov
Nonlinear waves of the reaction-diffusion (RD) type occur in many biophysical systems, including the heart, where they initiate cardiac contraction. Such waves can form vortices ca…
