FEATURES OF CHANGES IN CARDIAC ACTIVITY UNDER VIBRATION EXPOSURE
The results of the study have shown that when exposed to vibration, changes in cardiac activity occur in rabbits, the nature and direction of which depend on the parameters of the dynamic factor. Vibration with a frequency of 20 Hz causes moderate tachycardia, and 40 and 80 Hz – severe tachycardia. Three months of vibration in the first month of exposure causes tachycardia, and after three months of exposure, bradycardia. There is also a reduction in respiratory movements and a decrease in the activity of the enzyme succinate dehydrogenase.
