title: [ECG spectral analysis in quick death, during clinical death, and in the early postresuscitation period].
abstract: The article deals with the results of ECG amplitude-frequency analysis conducted in 17 experiments on dogs in the process of quick death, clinical death, and early postresuscitation period. In group 1 (8 animals) circulatory arrest occurred after ventricular fibrillation, in group 2 (9 animals) clinical death was induced by acute blood loss. The ECG was recorded in 3 orthogonal leads after Frank. The spectral analysis was conducted on a Cb-1-ts-02 spectrobiograph. The spectral form coefficient was calculated to study the relationship of the high- and low- frequency components of the spectrum. The total power of the spectrum was evaluated according to the sum value of maximum frequency peaks in 4 fixed ranges. Analysis of changes of the spectral components of the ECG signal showed them to occur in phases in the process of dying and in restoration of vital functions. The use of the method provides for a new quantitative and qualitative evaluation of the ECG.
