Method for identifying optimal regions for cardioversion therapy (variants)

Abstract

The group of inventions relates to medicine (physiotherapy). Electric stimuli which are generated by the following ringing circuit: active electrode-inductive storage unit-passive electrode-interelectrode tissues-active electrode, contain oscillations which are used as a test signal. In one variant of the method the electrodes are successively applied (in another variant—moved uniformly) across the skin area. Every time the electrodes-to-skin contact is detected, the oscillation parameters are recorded after a delay. Moreover, the values of parameters can be averaged. The group of invention provides the use of both combined and disjointed (separated) electrodes. An optimal zone for electropulse therapy is identified by minimal or maximal value of one or more parameters of the aforementioned oscillations and the use of the principle of “small asymmetry”. The group of inventions provides an increase in the accuracy with which zones optimal for electropulse therapy are identified and localized.
