This study was designed to develop a two-dimensional cellular model of uniform anisotropic muscle and to determine how irregularities of shape and variations in size of cardiomyocytes influence the passive (electrotonic) spread of currents ...

Using the boundary element method in conjunction with Tikhonov zero-order regularization, we have computed epicardial potentials from body surface potential data in a realistic geometry heart-torso system. The inverse-reconstructed epicardi...

This paper utilizes a structured and an unstructured grid representation of a torso with an anisotropic skeletal muscle to assess current distributions from defibrillation shocks. The results show that a finite-element solution on an unstru...

Applications of electrical stimulation to the nerve or muscles associated with a defunct limb joint due to stroke or spinal cord injury are a viable means of restoring a certain level of functional movement to the patient. In this article, ...
