Heart Condition Determination Method and System

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, the method comprising steps of:

• receiving ECG measuring data from the ECG recording device,
• determining vector cardiogram (VCG) data,
• receiving a model of the heart, preferably with torso, as an input, preferably based on a request comprising request parameters,
• obtaining the location information relating to a number of ECG electrodes relative to the torso model and/or heart a model of the subject,
• based on the location information in the torso model and/or heart model, positioning of the number of ECG electrodes,
• determining mean TSI data values representing the TSI path relating to an electrophysiological phase representing the ECG feature, the mean TSI providing a location within the heart representing the mean location of the ECG feature at the corresponding time,
• positioning the mean TSI path and preferably the vector cardiogram data points in the model of the heart and/or torso at an initial position, and
• rendering the model of the heart, preferably with torso, with the mean TSI path, preferably with VCG data related to the TSI, for displaying on a display screen for interpretation of the displayed rendering.
