THE DIFFERENCES IN CARDIOGRAM CHANGES FOR THE ARCTIC AND MID-LATITUDE ZONE INHABITANTS DURING THE GEOMAGNETIC STORMS

The analysis of changes in parameters characterizing a state of human cardiovascular system – the T-wave symmetry coefficient of the electrocardiogram (parameter T) – for the inhabitants of Tiksi and Yakutsk during the geomagnetic storms was fulfilled. It is shown that the increase in T parameter for the Arctic zone inhabitants is often observed two days before the beginning of storm, but maximum values of the parameter are achieved on the second or third day after the beginning of storm – in the recovery phase. For the mid-latitude city inhabitants (Yakutsk) the increase in T parameter two days before the beginning of the storm is not always observed, and the more significant maximum appears on the first day, i.e. in the main phase of storm.
