Resumen:
We performed a study of the systolic and diastolic arterial blood
pressure behavior under natural variables such as the atmospheric
pressure and the horizontal geomagnetic field component. We worked with
a group of eight adult hypertensive volunteers, four men and four women,
with ages between 18 and 27 years in Mexico City during a geomagnetic
storm in 2014. The data was divided by gender, age, and day/night cycle.
We studied the time series using three methods: correlations, bivariate
analysis, and superposed epoch (within a window of 2 days around the day
of occurrence of a geomagnetic storm) analysis, between the systolic and
diastolic blood pressure and the natural variables. The correlation
analysis indicated a correlation between the systolic and diastolic
blood pressure and the atmospheric pressure and the horizontal
geomagnetic field component, being the largest during the night.
Furthermore, the correlation and bivariate analyses showed that the
largest correlations are between the systolic and diastolic blood
pressure and the horizontal geomagnetic field component. Finally, the
superposed epoch analysis showed that the largest number of significant
changes in the blood pressure under the influence of geomagnetic field
occurred in the systolic blood pressure for men.
