Effect of geomagnetic storms on the erythrocyte sedimentation rate in ischemic patients

The dynamics of the erythrocyte sedimentation rate (ESR) in patients with i schemic disease shows a significantly different pattern in the days of rais ed geomagnetic activity as compared to quiet days. This is revealed by a gr eater intensity of ESR variations during geomagnetic storms as compared to the days of when there was little or no sun activity (quiet sun). Such beha vior of red blood cells reflects the patient's individual sensitivity to ge omagnetic field fluctuations. This article discusses a possible mechanism o f ESR variations.
