Abstract
Objective: to determine the characteristics of temporal variations in the dispersion mapping of ECG and HRV in cows and sport horses, as well as the early detection of possible pathological changes in cardiac activity.
Materials and methods. Cows and horses were studied in the work. The functional state of the heart of the studied animals was assessed with subsequent dispersion analysis using the CardioVisor-06s computer analyzer. The principle of operation of the device is based on the method of dispersion mapping of the electrocardiogram (ECG). The dispersion characteristics map in the CardioVisor-O6S device is projected onto the surface of a computer three-dimensional anatomical model of the heart, the so-called "heart portrait" or quasi-epicardium.
Results. The following results were obtained as a result of the research:
– a set of features of heart portrait images was proposed, allowing a more detailed description of cardiac activity in cows and horses using the CardioVisor-06S PTC;
– a method for expanding the diagnostic capabilities of the CardioVisor-06S software and hardware complex by analyzing the features of heart portrait images and identifying their characteristic values for various cardiovascular diseases is proposed;
– the use of this method is aimed at increasing the objectivity of assessing the results of analyzing an expanded set of output data obtained as a result of analyzing heart portrait images, taking into account the values of dispersion characteristics.
