This study investigated the synchronization between heart rate variability (HRV) in the low-frequency range and variations in geomagnetic induction in individuals with normal and high blood pressure. The results showed that there was significant synchronization between HRV and geomagnetic induction in individuals with normal blood pressure, indicating a potential risk of dysregulation of vascular tone in individuals with high blood pressure.
Synchronization between heart rate variability (HRV) in the low-frequency (LF) range (0.04-0.15 Hz) and 1-min variations in the components (X, Y, Z)and the total vector (F) of geomagnetic induction (nT) was studied in normotensive (blood pressure up to 140/90 mmHg) and hypertensive (blood pressure above 140/90 mmHg) individuals living in the Arkhangelsk region (60 degrees 51 ' 52 '' N 39 degrees 31 ' 05 '' E).The duration of registration of HRV for each person is 30 min in a sitting position. The most pronounced synchronization of the LF parameter, which reflects baroreflex activity, with variations in the GMF was found in normotensive individuals. The absence of a significant synchronization of the LF parameter with variations in the GMF components indicates a decrease in the sensitivity of the baroreflex mechanism and a risk of dysregulation of vascular tone, especially in people with arterial hypertension, under conditions of instability of the geomagnetic field.
