Abstract: The invention relates to a method of image analysis of a cardiac image of a human subject who has experienced a myocardial infarction. The method includes delineating an area of said image corresponding to scar tissue within myocardium, from the voxel data for said area, determining at least one value indicative of the likelihood of future cardiac arrhythmia, and optionally applying to said value a prediction matrix generated from the same value for other human subjects who have had a myocardial infarction and who have subsequently experienced cardiac arryhthmia.

Abstract: A system is provided for evaluating the probability that the outcome of an immediately following defibrillator shock will result in return of spontaneous circulation (ROSC) and for providing a decision support signal based thereon. The system includes electrodes and sensors, a module for measuring CPR and ECG related data from the electrodes and sensors, the ECG related data being measured and/or stored as ECG segments, an analysis unit connected with the module and adapted to calculate a property vector characterizing the condition of the heart from the ECG segments. The analysis unit is further adapted to calculate a probability indicator representing the probability that the outcome of an immediately following defibrillator shock will result in ROSC based on the property vector. The analysis unit is also adapted to generate a decision support signal relating to further treatment based on the property vector and/or the calculated probability indicator.
