| Abstract: | The effects of 4 Hz extremely low frequency Electromagnetic Fields (ELF EMF), Infrasound (IS) and hydrogen peroxide (H2O2) on Na+–K+ pump-induced transient inhibition of heart muscle contractility was studied. It was documented that EMF-treated and H2O2-containing physiological solution had synergic depressing effect on Na+–K+ pump-induced inhibition of muscle contractility, while the IS had elevation effect on it. On the basis of the obtained data
the H2O2 could be suggested as the messenger through which the stimulation effect of EMF on heart muscle is realised, while the relaxing
effect of IS on heart contractility is due to the decrease of CO2 solubility of muscle bathing aqueous medium. |
