ABSTRACT:
This invention incorporates the discovery of new principles which utilizes magnetic fluxes generated by time varying square wave currents of precise repetition, width, shape and magnitude to cause them to move through multi-turns of conductive material generally in the form of a coil, in order to stimulate the cardiovascular system in humans or animals by directing the fields externally through the chest wall or the skull in order to correct arrhythmias and/or heart blocks. The new method of cardiovascular stimulation evolved from experimental observations of cardiac muscle cells which when separated, oscillate at different frequencies and propagate at different rates at specific sites in and around the heart and a cell oscillating at a higher frequency when touching a cell oscillating at a lower frequency causes the lower oscillating one to speed up and synchronize at the higher rate. The Purkinje cells both in heart muscle and the brain appear to respond to the external magnetic fluxes and entrain, stepwise downward to the normal muscle contractile rate of about 1.25 Hertz. The repetition rate for normalizing a human heart lies between 7 and 8 Hertz, to within 1/100 Hertz for each patient, and a superimposed frequency at about ten times the adjusted rate has been seen to diminish or extinguish angina pain in some patients. A timer device, an adjustment device, and a device to deliver current to a coil which emits the magnetic flux is described. A theoretical model of the process is described.
