Influence of noise and vibration on nervous regulation of heart

Abstract

The authors studied influence of noise and vibration on cardiac nervous regulation in workers exposed to unfavourable work conditions. Evidence is that noise and vibration induce cardioneuropathy signs manifested in lower general vegetative influence on cardiac rhythm, as well as in its shift to higher activity of sympathetic nervous system. More marked changes are seen at daytime. Findings are that in combined influence of noise and vibration on humans, priority role of negative influence on cardiac regulation is taken by vibration factor.
