Introduction
The cardiovascular system consists of the heart and the vascular tree which distributes the blood
to the tissues of the body. Although the heart is somewhat independent and free running, it has neural
connections that can accelerate or depress its activity. Applied EMFs could influence heart function by
changing peripheral vascular resistance, by a direct action on the electrical system of the heart muscle,
or by a secondary effect via the CNS. The blood is a fluid that contains a variety of cellular elements
including the red and white blood cells. Red cells carry dissolved oxygen, picked up in the lungs, to the
body's other tissues; the white cells, in addition to protecting against invading microorganisms and
