Electrophysiological parameters of the HRV of animals with different vegetative status

Studies of the electrophysiological indicators of the VCR in the Cows of the Jersey breed with different levels of autonomic regulation were not previously carried out, and their normal values in the accessible literature are not described. Given the subtlety of the mechanisms of autonomic heart regulation, there is a need to expand the diagnosis of very common heart disease in animals. The purpose of research is to study the electrophysiological parameters of the variability of the heart rhythm in cattle to assess the possibility of including them in an integrated approach to the analysis of the functioning of the heart in animals. The 103 healthy cows of the Jersey breed studied. The dependence of the change in electrophysiological indicators of the variability of the heart rhythm on the vegetative status of the animal has been studied. To register cardio intervalograms, a computer complex electrophysiological laboratory “Conan - 4.5” was used. The recording was carried out in cattle in a calm state in a standing position. The electrophysiological indicators of the VCR were studied. In this regard, it is advisable to include the assessment of these parameters to include in the basic set of a complex of diagnostics of heart disease in cattle.
