title: [Estimation of electrode arrangement efficiency in measurement of coordinates of dipolar myocardium sources].
abstract: Identification of early disturbances in the process of myocardium depolarization and localization of coordinates of these disturbances in the heart contour is an urgent problem of modern electrocardiography. To solve this problem, it is necessary to identify signals of small disturbances in the depolarization process related to particular zones of disturbances in myocardium. Then, the identified signals are used to calculate the disturbance coordinates. In this work, a technique for estimation of partial sensitivity of electrodes to the position and orientation of the dipolar sources in myocardium is suggested. The results of calculation of partial sensitivity presented in this work make it possible to identify effective electrodes and minimize the total number of electrodes. The obtained results enabled us to suggest a system of electrodes for measurement of coordinates of the disturbance sources.
