Patent ID: 8412314

Claim:
A method for locating an ischemic region in the heart of a subject, the method comprising the steps of: establishing three dimensional coordinates axes with respect to the torso of the subject as a reference; establishing as a reference a multi-dimensional representation of the heart defining at least three dimensional coordinate axes of the heart, the multi-dimensional representation defining at least the base of the heart and a middle section of the heart; processing data from an electrocardiogram (ECG) with respect to measurements of the signals of at least three leads of the ECG, each lead signaling a measurement of a magnitude and a direction of an electrical vector associated with the heart of the subject; establishing the electrical center of the heart as the origin of the three dimensional coordinates axes with respect to the torso of the subject; establishing at least one horizontal axis of the three dimensional coordinate axes of the heart in the initial offset position to extend along the base of the heart; establishing at least one of the three dimensional coordinate axes of the heart in the initial offset position to pass through the electrical center of the heart; transforming the data from the ECG with respect to the measurements of the at least three leads of the ECG to substantially coincide with the three dimensional coordinate axes of the heart in the initial offset position; and rotating, with respect to at least one of the three dimensional coordinate axes with respect to the torso, the at least one of the three dimensional coordinate axes of the heart passing through the electrical center of the heart; and orienting the three dimensional coordinate axes of the heart from an initial position offset with respect to the three dimensional coordinates with respect to the torso of the subject to an imaginary position wherein at least one axis of the heart is parallel to or coincident with at least one of the three dimensional coordinate axes with respect to the torso of the subject.
