The present invention relates to a computer-implemented method for determining the electrical propagation of a subject's heart by external measurements, wherein the external measurements are taken from a subject's torso by locating a plurality of electrodes that provide an electrical signal responsive to heart activity.
The present invention is framed within the field of non-invasive estimation of epicardial electrical activity. The present invention defines a method for the automatic and non-invasive determination of the location of at least one portion of a subject's heart within the subject's torso. The present invention also defines a method for obtaining a three-dimensional model of at least one portion of the subject's heart.
A method for determining the cardiac potential of a subject includes providing as input data a torso model of the subject comprising a plurality of nodes, a cardiac model of the subject comprising a plurality of nodes, a cardiac activation sequence at the plurality of nodes of the cardiac model, and body surface potentials recorded on the torso of the subject; assigning to each node of the cardiac model a time-dependent weighting regularization coefficient based on the cardiac activation sequence; obtaining estimated cardiac potentials; obtaining estimated body surface potentials; determining a correlation coefficient between the estimated body surface potentials and the body surface potentials provided as input data; and determining if a predefined stop condition is reached based on the determined correlation coefficient.

SENSOR ARRAY AND SENSOR ARRAY SYSTEM FOR SENSING ELECTRICAL ACTIVITY
A device for measuring electrical potentials of a patient's body part, includes substrate nodes made of a flexible material and configured to be disposed on the patient's torso, wherein some pairs of substrate nodes are interconnected by straight portions of flexible material. The substrate nodes and straight portions of flexible material form a flexible substrate. The device includes electrodes, with each electrode disposed on a respective substrate node; and at least one connector. Each electrode is connected to the connector through a respective conductive path. Each conductive path is embedded in the flexible substrate formed by substrate nodes and straight portions. Only some straight portions connecting two substrate nodes have an embedded conductive path. The device removes one or more substrate nodes and corresponding electrodes by cutting portions which connect the substrate nodes with the remaining substrate nodes in the device, without interrupting the conductive paths of the remaining electrodes.
