RESUMEN
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.

Monitoring system is considered in this work as a reanimatologist-monitor-patient-medium system. This work is an upgrade to the previous concept of monitoring systems as systems with hybrid intelligence acting under variable conditions of object and medium. Human cardiorespiratory system was considered within the framework of the P. K. Anokhin theory of functional systems. The problem of resuscitation was formulated for this system and volume of required information was determined. Environment characteristics in resuscitation and surgery departments were considered. The requirements for monitor were formulated on the basis of analysis of these systems. The law of mutual adaptation of reanimatologist and monitor was put forward and safety problems associated with human factor were considered. Implementation of these principles in the MITAR 01-R-D is described.
