The influence of the previously recorded geomagnetic storm (GS) on human cardiovascular system and microcirculation has been studied under laboratory conditions. Healthy volunteers in lying position were exposed under two artificially created conditions: quiet (Q) and storm (S). The Q regime playbacks a noise-free magnetic field (MF) which is closed to the natural geomagnetic conditions on Moscow's latitude. The S regime playbacks the initially recorded 6-h geomagnetic storm which is repeated four times sequentially. The cardiovascular response to the GS impact was assessed by measuring capillary blood velocity (CBV) and blood pressure (BP) and by the analysis of the 24-h ECG recording. A storm-to-quiet ratio for the cardio intervals (CI) and the heart rate variability (HRV) was introduced in order to reveal the average over group significant differences of HRV. An individual sensitivity to the GS was estimated using the autocorrelation function analysis of the high-frequency (HF) part of the CI spectrum. The autocorrelation analysis allowed for detection a group of subjects of study which autocorrelation functions (ACF) react differently in the Q and S regimes of exposure.
先前记录的地磁暴（GS）对人体心血管系统和微循环的影响在实验室条件下进行了研究。健康志愿者取卧位，在两种人为创造的条件下进行暴露：安静（Q）和风暴（S）。Q 状态回放无噪声磁场（MF），其接近莫斯科纬度的自然地磁条件。S 状态回放最初记录的 6 小时地磁暴，依次重复四次。通过测量毛细血管血流速度（CBV）和血压（BP）以及分析 24 小时心电图记录来评估 GS 对心血管系统的影响。引入了心脏间隔（CI）和心率变异性（HRV）的风暴-安静比，以揭示 HRV 的平均组间显著差异。使用 CI 频谱高频（HF）部分的自相关函数分析来估计个体对 GS 的敏感性。自相关分析允许检测到一组研究对象，其自相关函数（ACF）在 Q 和 S 暴露状态下的反应不同。
