Evolutionarily, a human organism is adapted to the natural geomagnetic environment and its slight alterations. However, during geomagnetic storms (GMSs), the strength of the geomagnetic field (GMF) sharply increased hundreds of times and can pose a serious threat to people. We examine the effects of controlled compensation in the time-varying compo...
We tested the hypothesis whether the geomagnetic field (GMF) when disturbed can have effects on human autonomic nervous system (ANS) causing specific sensitive stress-reactions. Experiments were performed in both: natural conditions on days of low and high GMA and by the simulation of different GMA using the device of geomagnetic storms (GMSs) comp...
Background: The geomagnetic environment is very sensitive to changes in "Space weather" (SW) and its manifestations on the Earth. The human body is adapted evolutionarily to the slight alterations of the geomagnetic field (GMF). Objective: The aim of this work is to test the hypothesis on whether different levels of GMF causing specific stress-reac...
Over the last few years, various researches have reached the conclusion that cosmic ray variations and geomagnetic disturbances are related to the condition of the human physiological state. In this study, medical data concerning the number of incidents of different types of cardiac arrhythmias for the time period 1983–1992, which refer to 1902 pat...

The most objective index for the assessment of systolic function can be derived from the left ventricular end-systolic pressure-volume relation (ESPVR). But the main issue is to construct this function by means of non-invasive method and in the steady-state condition. The parameters which can be used for the construction of the contractility's curv...

P-553: Influence of helio-geomagnetic factors on the cardiovascular system
Levan Tvildiani1, Tamar Chlaidze1, David Tvildiani1, Otari Khomeriki1 and Irina Mikaberidze11AIETI Medical School, Tbilisi, Georgia; Internal Medicine, Georgian State Medical University, Tbilisi, Georg...
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 stat...

... A few studies have indicated that the exposure of adult humans to HMF leads to decreased heart rate and increased heart rate variability (Gurfinkel et al., 2016;Demin et al., 2021). Long-term monitoring of cardiac activity indicated a relationship between heart rate variability and weak natural geomagnetic variations in rabbits (Chibisov et al., 2004;Gmitrov and Gmitrova, 2004), rats (Kuzmenko et al., 2019), and humans (Chernouss et al., 2001;Janashia et al., 2022). ...

... Research shows that daily activity of the autonomic nervous system not only responds to changes in solar and geomagnetic activity, but is also synchronized with time-varying magnetic fields associated with geomagnetic field line resonances and Schumann resonances that coincide with physiological rhythms [9], [10], [11] and may affect human health [12], [13], [14]. ...
... Over the last years, the Cosmic Ray Group of the National and Kapodistrian University of Athens (NKUA) has intensively worked on how the human physiological state may possibly be effected by space weather phenomena and has published a significant number of scientific papers presenting the results of these investigations (Papailiou et al. 2009(Papailiou et al. , 2011Mavromichalaki et al. 2012Mavromichalaki et al. , 2017Mavromichalaki et al. , 2021Giannaropoulou et al. 2014;Galata et al. 2017). In this work, an attempt to present a synopsis of the studies on heart rate (HR) variations that have been conducted by the NKUA in Greece so far is being made. ...

... 7-cm solar radio flux, earth-ionosphere cavity or Schumann resonances [6], etc.) all of which are indicated or described by quantitative parameters or indices (sunspot Rz index, geomagnetic aa index, ozone concentration, etc.). Most of these components or indices exhibit an established seasonality (annual cyclicity) but their chronomes are often multicomponent, with transyear (periods longer than 12 months but shorter than 24 months) or infrannual (multiannual) cycles such as the 11-year cycle of the sunspot index (Rz index or Wolf number) which has been a consistent observation over hundreds of years [5][6][7][8]. However, whether or not such cyclical patterns in malaria incidence or admissions and HGA are interconnected, remains still to be confirmed. ...
