Aim of study (acc. to author)

To investigate physiological changes on cardiovascular regulation in rabbits caused by the influence of disturbances of earth geomagnetic field.

Background/further details

The Kakioka Magnetic Observatory supplied the values of geomagnetic field (GMF) disturbance.

Main outcome of study (acc. to author)

This study provides evidence that GMF disturbance is associated with (1) weaker baroreceptor function and (2) decreases in spontaneous cardiovascular variability estimated by heart rate variability and blood pressure variability.
