Alternative approaches to clinical electrophysiology

Purpose: Creation of a device and a new methodology for registering an electrocardiogram that does not require fixation of dogs and impose electrodes.

Materials and methods. Two groups have formed that included clinically healthy 12 dogs of small breeds with a weight category of 10 kg, age restrictions were from 3 to 5 years. Electrocardiograms were recorded as a standard veterinary electrocardiogram, so on the CONAN hardware and software, using standard I, II, III ECG of lead. Electrodes "Crocodile" were fixed on the skin of the pelvic folds, the skin near the elbow joint. The second stage of the study was based on the creation of a contact platform capable of registering a nervous impulse. The proposed methodology for registering electrophysiological activity of the heart is based on the creation of mycal electrodes that can perceive indications in the position of the studied animal standing, excluding a stressful effect, lowering the degree of excitation. The third stage of the study was to register an electrocardiogram through a contact site, followed by assessment and comparison with classical methods.

Results. In the testimony of atrial and ventricular complexes, when using both methods, there were no differences. The amplitude is preserved, the distance between the intervals did not change. During the observation, the lack of pronounced excitement in dogs was revealed when using the simulated site, which, in turn, facilitates the interpretation procedure. The observation revealed a reduction in the time spent on research when using an experimental methodology.
