Fluctuation of energy of spectral components of the EEG signal during dying, clinical death and early period of resuscitation

Fluctuation energy of spectral analysis containing ECG signals were studied in 17 experiments before the modeling of fast death. In the early period of resuscitation ECG recordings were done in 13 orthogonal leads (Frank method). On each lead 5 cardiac cycles were registered with the analysis of 2 components of the ECG: complex QRS and T-wave. In the analyzed period the phase changes for coefficient fluctuations were established. The authors express supposition, that the low meaning of coefficient fluctuations appear in the process of compensation, but high meanings--just like an explosion of compensation.
