RESUMO
Analysis of heart rate variability (HRV) provides the possibility to obtain the predictive and meaningful information on the functional status and features of adaptive responses of the whole organism. Monitoring the functional state in the course of professional activities with the use of wireless cardiorhythmography provides data acquisition on heart rate dynamics in accordance with the level of occupational load. The article is devoted to the development of methods for rapid assessment of the functional state of motor vehicle drivers in the process of occupational activity. There was performed the hygienic assessment of working conditions of jobs. The studies of the influence of the factor loadings on the level of the functional state of the cardiovascular system (CVS) of drivers were performed with the help of wireless telemetry system. A developed computer software were used for the calculation of the spectral parameters of HRV. By the analysis of cardiorhythmograms in drivers there were both revealed significant disorders of the rhythm of the cardiac activity (reduction of total power TP, HF-component, increase in LF-component, LF/HF index, extrasystole) and recorded changes in the spectral HRV indices in accordance with the level of occupational load, that represents the degree of individual response. The method of wireless cardiorhythmography is promising for the creation of personalized monitoring system to assess the risk of individual occupational risk.
