Method of estimation of stability of the bioelectric signal

The statistical method for estimating the stability of transient bioelectric signals is analysed. Modal values of bar charts computed by sliding sample of pulse counts are proposed to serve as a stability index. The destabilization index is also derived. It serves as a current estimate of the biological object status in response to external exposures. A noise immunity of the method for a noisy pulse model is computed. Some results of clinical testing of the method as applied to the task of the current estimate of fetus conditions on the basis of rhythmographic data are presented.
