Summary:
Over the last few years various researches have reached the conclusion that
cosmic ray variations and geomagnetic disturbances are related to the condition
of the human physiological state. In this study the medical data used, were
registered during two experiments conducted at different times and different
places, and were analyzed in relation to daily variations of cosmic ray and
geomagnetic activity. Specifically daily data concerning mean values of heart
rate and arterial diastolic and systolic blood pressure were registered during
the medical examinations of a group of 4018 Slovak aviators and data concerning
the incidents of four types of cardiac arrhythmias (Supraventricular
extrasystols, Supraventricular paroxysmal tachycardia, Ventricular single
extrasystols, Ventricular multiple extrasystols) were registered during 24-hour
Holter monitoring and electrocardiography records from different hospitals of
1902 patients in Tbilisi, Georgia. These particular studies refer to the time
periods 1 January 1994 till 31 December 2002, and 1 January 1983 till 31
December 1992 respectively. The Pearson r-coefficients were calculated and the
Analysis of Variance (ANOVA) method was applied to establish the statistical
significance levels (p-values) of the effect of solar and geomagnetic activity,
and cosmic ray intensity (CRI) variations on the aforementioned physiological
parameters. The effect of CRI and geomagnetic variations up to three days
before and after geomagnetic storms and CRI decreases and increases on heart
rate and arterial diastolic and systolic blood pressure was also investigated
by the help of ANOVA and superimposed epoch method. The p-values were
calculated for the days before (-), during (0) and after (+) geomagnetic storms
and CRI variations. Results show that there is an underlying effect of
geomagnetic activity and cosmic ray intensity variations on the cardiovascular
functionality
