Functional properties of the myocardium are mediated by the tissue structure. Consequently, proper physiological studies and modeling necessitate a precise knowledge of the fiber orientation.… Expand
Simulating the electrical behavior of cardiac tissue using the bidomain model.

- Critical reviews in biomedical engineering
The complex microstructure of cardiac muscle comprised of coupled cells, enveloped by an interstitium made up of blood vessels, connective tissue, and fluid, presents some obvious problems to those… Expand
Electrotonic influences on action potential duration dispersion in small hearts: a simulation study.
Intrinsic spatial variations in repolarization currents in the heart can produce spatial gradients in action potential duration (APD) that serve as possible sites for conduction block and the… Expand
Loading effect of fibroblast-myocyte coupling on resting potential, impulse propagation, and repolarization: insights from a microstructure model.
The numerous nonmyocytes present within the myocardium may establish electrical connections with myocytes through gap junctions, formed naturally or as a result of a cell therapy. The strength of the… Expand
Study of atrial arrhythmias in a computer model based on magnetic resonance images of human atria.
The maintenance of multiple wavelets appears to be a consistent feature of atrial fibrillation (AF). In this paper, we investigate possible mechanisms of initiation and perpetuation of multiple… Expand
Modelling cardiac fibroblasts: interactions with myocytes and their impact on impulse propagation.
AIMS Existence of myocyte-fibroblast coupling in the human heart is still a controversial question. This study aims at investigating in a biophysical model how much coupling would be necessary to… Expand
Hybrid Finite Element Method for Describing the Electrical Response of Biological Cells to Applied Fields
A novel hybrid finite element method (FEM) for modeling the response of passive and active biological membranes to external stimuli is presented. The method is based on the differential equations… Expand
A finite volume model of cardiac propagation
This paper describes a two-dimensional cardiac propagation model based on the finite volume method (FVM). This technique, originally derived and applied within the field of computational fluid… Expand
Continuous Oximetry/Capnometry Monitoring Reveals Frequent Desaturation and Bradypnea During Patient-Controlled Analgesia

- 1 August 2007
BACKGROUND:The most serious complication of patient-controlled analgesia (PCA) is respiratory depression (RD). The incidence of RD in the literature is derived from intermittent sampling of pulse… Expand
Genesis of complex fractionated atrial electrograms in zones of slow conduction: a computer model of microfibrosis.
BACKGROUND Complex fractionated atrial electrograms are used as potential targets for catheter ablation therapy of atrial fibrillation. Although fibrosis has been associated with the presence of… Expand
