20140278324 | Interactive Tissue Model for Simulating the Electrical Activity of Excitable Tissues - A method of simulating electrical propagation in the heart muscle on a computing device having a processor and a memory includes providing a structural representation of a heart muscle. The structural representation includes a plurality of tissue elements. The plurality of tissue elements have a shape corresponding to shape of a heart muscle. The method includes storing a model of electric potential propagation through the structural representation in the memory. The model includes a piecewise linear equation describing electrical activity within each tissue element and a difference equation describing conduction from one of the tissue elements to an adjacent tissue element. The method also includes providing a first set of tunable parameters for inclusion in the piecewise linear equation and a second tunable parameter for inclusion in the difference equation. The method further includes tuning the first set of tunable parameters and the second tunable parameter in the model. The method also includes running said model on the processor of the computing device and displaying the simulated electrical propagation through the heart muscle over time. | 09-18-2014 |
