Summary:

The purpose of the study is to evaluate psychoemotional features of volunteers residing in the middle latitudes and the impact of emotional stress on the synchronization status of the myocardium and heliogeomagnetic disturbances. Material and Methods. In the course of 60 days volunteers (31 people) were daily assessed concerning the state of the myocardium according to the coefficient of symmetry of the T-wave (CST) in the phase portrait of ECG at rest, after emotional stress, and after rest. Geomagnetic activity was assessed with the help of global planetary index of geomagnetic activity (Kp- index), while psychoemotional state of volunteers — with the help of questionnaires and projective techniques. Results. Personality characteristics of volunteers residing in the middle latitudes include optimism and friendliness, combined with a reduction of adaptability when building stress coping behavior against the background of polar intrapsychic tendencies. Emotional stress causes transient change in the synchronization state of the myocardium and heliogeomagnetic disturbances (CST-Kp). 3 types of violations of CST-Kp synchronization were identified. We were the first to describe the phenomenon of CST-Kp synchronization inversion: the increase of myocardium tension after geomagnetic disturbance reduction. Conclusion. Emotional stress in volunteers residing in the middle latitudes against the background of their characteristic of reduced psycho-emotional adaptation, leads to blockage of myocardium's reaction to weak geomagnetic disturbances and may contribute to the emergence of sensitivity to powerful geomagnetic disturbances.
