Abstract: A computer implemented method for processing measurement data from electrocardiogram, ECG, electrodes on a subject. The method includes obtaining a 3D anatomical model of the torso of the subject, and obtaining a 3D image of the torso of the subject. The three dimensional image is aligned with the three-dimensional model. A position of each electrode in the three-dimensional model is determined from the three dimensional image. The positions of the electrodes in the three dimensional model are used for estimating the distribution, fluctuation and/or movement of electrical activity through heart tissue.

Abstract: The invention relates to a method and a system for providing a representation of synchronicity of electrical activation of heart tissue. The method includes obtaining a three-dimensional model of electrical activation of the heart. The three-dimensional model includes a mesh with a plurality of nodes, each node having associated therewith a time delay between stimulation of the heart at a stimulation site and activation of the heart at that respective node. For each node a stimulus site is defined at the location of that node. For each node a modified three-dimensional model of electrical activation of the heart resulting from stimulation at that node is determined. For each node a measure for heart activation synchronicity for the heart based on stimulation at that node is determined A heart synchronicity map is determined representing a three-dimensional model of the heart, indicating at each node the respective measure for heart activation synchronicity.
