The Cardiac and Hemodynamic Indices of the Young Men Undergoing the Influence of the Weak Electromagnetic Fields in the Sound Range


The cardiac and hemodynamic indices of the young men undergoing the influence of the weak electromagnetic fields in the sound range. We aimed to assess the effect of the sound range weak electromagnetic field on the autonomic nervous system. The method of the heart rate variability analysis was chosen for the characterization of the functional state on the autonomic nervous system. The hemodynamic and functional state of the left ventricle was assessed on the base of: ejection fraction, cardiac output, common peripheral resistance, maximal end-systolic elastance of the left ventricle and the data of a sphygmomanometry. The practically healthy young men (n=40) of the age 18-22 were investigated. The inductance was altered stepwise. A subject was influenced in turn with the one of the fixed frequencies. Different correlations of functional activity of the autonomic nervous system’s parts determine heterogeneous reactions of organisms on the influence of electromagnetic field. A mechanism of the influence of electromagnetic field on cardiovascular system, to some extend, is determined by a type of the autonomic balance of an organism
