The present invention relates to a method, such as implemented on a computer, for performing of a location determination for determining of a candidate area of a heart disorder, such as a PVC (premature ventricular contraction) causing part of the heart muscle, while applying information from an ECG device and a processing unit: - obtaining a torso model and or a hard model of a subject, -for the purpose of determining locations, determining of an origin in the hearts model and torso model, such as in the proximity of the center of the heart, - obtaining the location information relating to a number of ECG electrodes relative to the torso model and or hearts model of the subject, - based on the location information in the torso model and/or heart model, positioning of the number of ECG electrodes, - obtaining of electrode measuring information, such as embodied by means of electrode vector, related to respective distinct ECG electrodes, - constructing weighted, such as preferably normalized, vector is based on electrode measuring information while applying a predetermined ECG feature, - relating the weighted vectors to the origin and the respective electrodes, - based on the weighted vectors relative to the said origin, constructing of an initial anatomical feature vector determining an initial anatomical feature geography and determining a direction towards the candidate area.
