Abstract
There has been studied a bio-efficiency of geomagnetic variations in the sub-auroral latitudes (Yakutsk) in the minimum of the 24th 11-year solar cycle activity (2019) according to the parameters of the solar wind, Bz-components of interplanetary magnetic field, solar radiation with a wave length of 10.7 cm. There has been also analyzed a meteo factors’ impact (air temperature, air humidity, atmosphere pressure and wind velocity) in the given period. The condition of the cardiovascular system has been estimated daily (March-April of 2019) by a t-wave symmetry coefficient (TSC) in a phase portrait of the ECG. The research has been organized as a part of a simultaneous multi-latitude monitoring “Heliomed-2”. In the volunteers from sub-auroral latitudes there have not been revealed any disorders of the myocard repolarization in the minimum of the solar activity, according to the TSC in the electrocardiogram phase portrait. Cardio-sensitivity (myocard respond to more than 67% of the geomagnetic activity) has not been revealed in the volunteers. The cardiovascular system of the examinees from the sub-auroral latitudes responded only to 45.5% of the geomagnetic variations, most of which was characterized by high parameters of the solar wind dynamic pressure. Also, the respond of the myocard of the volunteers has been revealed to change of the atmospheric pressure, while temperature, air humidity and wind velocity did not impact the organism.
