The article considers the novel method for ECG spectral analysis based on psophometric and spectral deviometric devices or algorithms. This article is the reply for previously published article «Correction of the recording artifacts and detection of the functional deviations in ECG by means of syndrome decoding with an automatic burst error correction of the cyclic codes using periodograms for determination of code component spectral range. Part II: Old mathematics for the novel applied problems of cardiometry».
