ABSTRACT
Electromagnetic Fields approaches, devices, and methods that relate to its potential utility in the mentioned categories have been proposed and evaluated and, in some cases, have demonstrated functional utility for detection and treatment. Cardiac transmembrane ionic currents associated with myocardial depolarization and repolarization sweep through the heart causing it to contract and then relax resulting in blood pumping and refilling, respectively. Detection of the magnetic field associated with cardiac currents can be a useful adjunct to other diagnostic monitoring methods. Transcutaneous magnetic stimulation is a rapidly growing electromagnetic application and, as the name implies, is the use of pulsed electromagnetic fields (PEMF) to stimulate brain tissue with applicator coils placed on the scalp surface. The possibility that exposure to low-intensity PEMF could reduce the negative effects of experimental myocardial infarction was carefully investigated using a rat model.
