Assessment the dynamics of ECG parameters interactions during invasive procedures

Abstract

The signals dynamic interactions characterizing individual systems are very significant to the human body, as complex adaptive system, functions’ analysis. The aim of presented work was evaluation of the impact to cardiovascular system function of two invasive procedures, i.e. instrumental recanalization of heart vessels and radio frequency ablation of heart rhythm disorders The method designed for extracting information in time series generated by complex living systems and based on the matrix theory with considering the inter-parameter relationships obtained during monitoring of ECG was used. The investigated contingent consisted of three groups of pts. The first group contains 53pts with anterior myocardial infarction, the second group – 40pts with inferior myocardial infarction, and both group pts underwent the coronary recanalization procedures. The third group contains 21pts with heart rhythm disorders which underwent the radio frequency ablation procedure. The study results permit to conclude that every pathology in human organism have its own “face” i.e., changes interactions between different organs and create its own attractor. The myocardial infarction of different localizations has different influence to heart – organism interactions. Matrix analysis allows evaluating the changes of interactions in human organism during invasive procedures.
