Electrical conductivity values used with the bidomain model of cardiac tissue
TLDR
Electrical conductivities in the bidomain model of cardiac tissue are expressed as functions of four parameters, which allow simulations to be performed using nominal, equal, and reciprocal anisotropy without introducing undesired effects, such as length constant variations.Abstract:
Electrical conductivities in the bidomain model of cardiac tissue are expressed as functions of four parameters. These expressions allow simulations to be performed using nominal, equal, and reciprocal anisotropy without introducing undesired effects, such as length constant variations. Relative values of the bidomain conductivities are estimated to be: /spl sigma//sub iL/=1, /spl sigma//sub iT/=0.1, /spl sigma//sub eL/=1, and /spl sigma//sub eT/=0.4.read more

A Comparison of Monodomain and Bidomain Reaction-Diffusion Models for Action Potential Propagation in the Human Heart
TL;DR: It is concluded that, in the absence of applied currents, propagating action potentials on the scale of a human heart can be studied with a monodomain model.

Tissue engineering of electrically responsive tissues using polyaniline based polymers: a review.
TL;DR: It is concluded that electroactive PANI and its derivatives show great promise in eliciting favorable responses from various cell lines that respond to electrical stimuli, and are therefore effective biomaterials for the engineering of electrically responsive biological tissues and organs.

Computational techniques for solving the bidomain equations in three dimensions
TL;DR: It was possible to speed up solution of the bidomain equations by an order of magnitude with a slight decrease in accuracy, and direct methods were faster than iterative methods by at least 50% when a good estimate of the extracellular potential was required.

Directional differences of impulse spread in trabecular muscle from mammalian heart.
TL;DR: The value of the transverse internal resistance can be accounted for on the ground of frequent branching in a three‐dimensional network and there is no need to make the additional assumption of current flow through lateral low resistance pathways between parallel fibres.

Electrical constants of trabecular muscle from mammalian heart
TL;DR: The passive electrical properties of muscle bundles obtained from the right ventricle of sheep or calf hearts were determined through extracellular electrodes and constant current pulses were made to flow between the ends of the bundles.

TL;DR: Experimental findings confirm the experimental finding that the potentials around a wave of depolarization cannot be accounted for by the conventional hypothesis that the wavefront is a uniform double-layer current source.
