This study investigates how infrasound exposure should influence the electrocardiograph (ECG) patterns and the functioning of the cardiovascular system. Infrasound waves are widespread and common and now perceptible in the working environment (particularly in industry) as well as in the recreation grounds (natural sources of infrasounds). the main sources of infrasounds include heavy machines, transport and materials handling installations, as well as natural phenomena, such as blowing winds, storms or flowing waters. Research work has now established that low-frequency noise affects the morphology of the electric biopotentials of human brain and influence the blood pressure, the level of electrodermal activity and visual-motional coordination in humans. the effects of infrasounds on fluctuations of the ECG patterns have received little attention so far. This study summarises the research data to determine how low-frequency noise with frequency f = 7 Hz and the acoustic pressure level SPL=120 dB (HP) should influence the ECG patterns. Experiments were performed on a group of 33 participants. Thus obtained experimental data indicate that infrasound exposure leads to major changes in the functioning of human heart.
