System and method for reconstruction and visualization of cardiac electrical activation.

System for reconstruction and visualization of cardiac electrical activity, high precision, given that improves the performance of existing systems by including the prior information of bioelectric problem in a learning algorithm, and exploiting the temporal correlation and by spatial interpolation and decimation subsystems. The system comprises at least: a plurality of catheters, non-specific to the system design; means for obtaining the coordinates of the location of said array; means providing the geometry of the heart wall; processing means the signal from the array of catheters, based on implementing a Support Vector Machine algorithm that allow incorporation of bioelectric phenomena; interpolation means and exploitation of redundancy that allow to obtain high resolution without investment matrix; and display means.
