Myocarditis and PEMF

Extremely low frequency (ELF) EMFs easily penetrate tissues and cause virtually no sensory reactions. The reaction of the cardiovascular system to ELF EMFs is complex and includes direct responses of cardiac muscle, the autonomic nervous system, blood vessels, etc., and reflex responses mediated by the central nervous system. ELF EMFs increase the diameter of capillaries and greatly improve microcirculation, systemically and locally in the heart itself.

High frequency and high strength EMFs undoubtedly affect the cardiovascular system. Laboratory studies show that effects result even from EMFs below 150 Hz and 1G. The cell membrane is the primary site of EMF interaction, leading to intracellular changes in gene function and protein synthesis. These effects are highly nonlinear, with dose-response patterns that show “windows” of action and resonance-like phenomena. Power transmission lines can have health effects, but electrical transportation systems and electrical appliances are more common sources and have much more powerful EMFs. Movement in the environment interacts with other external EMFs and work synergistically together to cause bioeffects. New lower limits to field strength actions are often discovered. There are no known lower limits for the intensity of EMFs to affect biological systems. Only the microscopic design of a receptor in the body and the time-variation dependency of its interaction with the many varied EMFs define the level of sensitivity to EMFs.

Extremely weak alternating, sinusoidal (power line) fields of certain frequencies interact with the local geomagnetic field and/or with EMF therapeutic systems. EMFs can act through another organ or tissue’s EM field, local and/or atmospheric geomagnetic fields and possibly even the moon. Even the body’s electrical currents interact with external fields and participate in control of life processes. External EMFs interact with most, if not all, organs and functions in the body.  All these interactions clearly paint a very complex picture of EMF actions on the body – leading to the natural conclusion that human functioning is fundamentally inseparable from the EMFs around it.

ELF (below 300 Hz) EMFs interact strongly with biological systems, both electrically and magnetically. The magnetic field aspect of an ELF EMF penetrates the body without obstruction since the magnetic permeability of tissue equals that of air. Effects are directly related to the strength of the electrical currents induced in the tissue by the magnetic field aspect. Effects are seen at current strengths close to natural currents in the body and even fields well below those of natural tissues cause cellular responses. These involve membrane signal systems, cell surface receptors and all body biochemical systems, including enzyme activity and gene expression.
