Patent ID: 8660639

Claim:
A method of noninvasive electrophysiological study of the heart, comprising the following steps: attaching one-off registration electrodes on a chest surface, ECG-registering in several unipolar leads from the chest surface: processing ECG-signals in real-time mode, retrospective processing the ECG signals, generating a computer (CT) or magneto-resonance (MRT) tomography of the chest of a patient with the attached electrodes, constructing and editing computer voxel models of organs of the chest and the heart, constructing polygonal models of a torso and the heart with the help of a computer program; determining coordinates of the registration electrodes on the chest surface; interpolating values of the ECG-signals in nodes of a polygonal grid and obtaining isopotential maps on a polygonal model of the torso; reconstructing an electric field potential at given points of the chest, epicardial surface of the heart, interventricular, and interatrial septa surfaces; producing a visualization of results of reconstructing the heart electric field including epicardial electrograms, isochronous and isopotential maps, and propagation maps on the models of the heart and its structures; and clinically evaluating the results.
