The aim of the present article is to research the response of the cardiovascular system of healthy volunteers to change in heliogeomagnetic activity in subauroral area (Yakutsk) in the minimum (year 2009) and in the maximum (year 2014) of the 24th 11-year solar cycle. The condition of the volunteers' cardiovascular system has been estimated according to the T-wave symmetry coefficient in the electrocardiogram (TSC), which displays the processes of myocard repolarization. Heliogeomagnetic activity has been estimated by a daily Kp-index parameter of geomagnetic activity during the total period of the experiment. In October - December of 2009 there have been examined 19 persons, and in March - April of 2014 - 17 persons. To find the response of the cardiovascular system of the volunteers on the change in heliogeomagnetic activity, there has been done an analysis of temporary coincidence of the maximum of Kp-index and of the maximum of the TSC variations. The ?2 method has been used for differentiation of the respond of the cardiovascular system of the volunteers to changes in geomagnetic activity in the maximum and in the minimum of the solar activity. It has been established that in the minimum of the 11-year solar activity in 2009 the coincidence of the maximums of TSC and Kp was 77,8%, and in the maximum of the cycle in 2014 - 71,4%. Statistically significant difference of the myocard response to geomagnetic activity on the period of the minimum and maximum of the 11-year solar cycle has not been revealed (p>0.05). Though, it has been found that the coincidence of the TSC maximum and the Kp maximum, as in the minimum as in the maximum of the 11-year solar cycle, has been observing with the Kp daily parameter not higher than 15 relative units. From there, the revealed uniformity of the response of the volunteers' cardiovascular system on the geomagnetic change, independently on the period of the minimum and maximum of the 11-year solar cycle, displays the versatility and resistance of the human adaptation mechanism to the space weather factors. In future this will help to reveal the features of the cardiovascular response to the geomagnetic activity in patients with an arterial hypertension and ischemic heart disease, in persons from different age groups.
