The classification of P-wave and QRS-complex on electrocardiosignal within the correlation theory for heart arrhythmias detection

Methods of automated processing for electrical cardiac signal are considered in the article. Ways to expand the list of diseases to be diagnosed by the P-wave shape analysis are proposed, as well as the technique to increase the detection accuracy of heart’s ventricular late potentials. Algorithms of QRS-complex classification by its shape based on the estimation of mutual covariance and optimal estimation of the P-wave parameters based on statistical models are described.
