Abstract: The present invention relates to a method to provide a mean temporal spatial isochrone (TSI) path relating to an ECG feature (wave form) of interest, such as the activation of the heart from a single point (QRS), relative to the heart in a torso while using an ECG measurement from an ECG recording device.

Abstract: The present invention relates to a method to be performed by a computing device part of or coupled to an ECG device for applying a marker element in a process of determining positions of a set of ECG electrodes as placed on a human torso relative to a 3D model of a body, preferably a torso model of the torso of the human body. The method includes receiving an imaging information recording relating to the human body from an optical imaging device, preferably a 3D imaging device. The optical imaging information includes imaging information of the exterior of the body, such as imaging information of the exterior of the torso, and imaging information of the marker element. The method also includes performing an image recognition on the imaging information for obtaining a presence determination, preferably a positive or negative determination, of the marker element in the imaging information.

Abstract: Various embodiments include methods of cardiac resynchronization therapy (CRT). Various embodiments may include: generating, using a processing unit, a cardiac activation map including a three-dimensional (3D) heart model of the heart that shows coronary vessels of a patient and shows the propagation of electrical signals through the 3D heart model; determining the location of a left bundle branch block (LBBB) based on the cardiac activation map; implanting a first pacing device and a second pacing device into the patient; stimulating the His Bundle of the heart using the first pacing device; and stimulating the left ventricle (LV) of the heart at a position downstream of the LBBB with respect to a direction of electrical conduction through the LV using the second pacing device after stimulating the His bundle.

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.

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.
