To investigate the interrelated effect of artificial static magnetic fields (SMF), natural geomagnetic fields (GMF), and verapamil on blood pressure regulation in rabbits. Verapamil is a calcium channel blocking agent.

Disturbance in the geomagnetic field (GMF) decreased baroreceptor sensitivity, whereas static magnetic field (SMF) showed the opposite effect. Verapamil blocked the SMF and GMF effect on baroreceptor sensitivity. These findings indicate calcium channels as possible targets of exposure.
