title: [A system of electrode arrangement for measurement of the coordinates of sources in the myocardium area].
abstract: A system of electrode arrangement for localization of zones of small depolarization abnormalities in human myocardium is suggested. Standard electrodes R, L, F and Frank electrodes H, M compatible with standard methods of examination. The total number of electrodes in the system is 15. A technique for reconstruction of the coordinates and orientation angles of the abnormality sources from measured electrode potentials is suggested. Statistical modeling is used to assess the dependence of the reconstruction error on the source position and orientation. The maximal error of coordinate measurement is found to be approximately 1.5 mm; average error, 0.75 mm.
