【正文】 agic field and the toad which pulsate weakly. There is discrepancy between the pulsatile a each toad which stimulated by magic field. This is dividual discrepancy, it is related with the strong of the experiment animals. But if pared these pulsatile amplitudes of toads which stimulated by magic field with amplitude of the toad which pulsated weakly at the same time of discrepancy is very not obvious. VI. CONCLUSIONS There are a P wave and a QRS wan the pulsatile curve with the electrocardiogram to we can discover that the P wave that express atrium constriction is earlier than atria ORS wave that express ventricle constriction is earlier than ventricle constriction is earlier than ventricle wave. Heart constriction connected closely with the change of biological electricity of cardiac muscle. Before heart contracts,must occur on muscle cell membrane a movement potential that can be conducted, pass through then excitedcontract unite can just arouse muscle cell contract to respond. The P wave and QRS wave of electrocardiogram reflect atrium and ventricle respectively with the electrical change in polarization course. Atrium wave and ventricle wave reflect atrium and ventricle respectively the mechanical campaign. Mechanical campaign is only initiated from electrical campaign. So P wave is earlier than atrium wave, QRS wave are earlier than ventricle sixth toad which wave. When the pulsatile rhythmically of heart stopped or in electric attack would be helpful on clinic data. The magism stimulation may have the same effects as the electric stimulation based on electromagism. The pulsatile curve of toad which just exposed heart can divide into atrium wave and ventricle wave. After a time, heart is weak gradually, right now, heart contracts intensity weakens obviously. Atrium wave can not already distinguish with ventricle wave on the curves of toad weak pulsatile curve Original two summit curves change to single summit curve,and contract range reduces obviously. Do not go to the half of original atrium wave. But heart pulsatile period still ask 1 second. Stimulate toad heart, the direction of magic field vertical cross toad heart center from the back to belly. Take Toad 6 notes at once, the pulsatile curve of toad recovery became original two summit curves. And the amplitude of ventricle six toads which wave worth than single wave is in height result proves that the magic stimulation of high energy can promote toad heart strength obviously, but for the pulsatile curve period does not be acted on obviously. Can make the curve of pulsatile curve already can not be districted the atrium wave and ventricle of the weak heart recovery that atrium constriction with ventricle constriction alternately. The cell of cardiac muscle has special electrical stimulate can affect the electrical physiology moving of heart obviously. Magic field and electric field have the characteristic that changes mutually. The role of extra magic field can also arouse the ion current in the anism toad 7 cell of cardiac muscle to occur change. Therefore, it changes the electrical physiological campaign of the cell of cardiac muscle, change heart contract condition. Compared with direct electrical stimulation, the magic stimulation has a lot of advantages. It shows by clinical information, eliminate the heart shake of human body with current (go through chest wall) to need the energy of 150350 J probably, directly eliminate heart shake to need the energy of 1624 J probably. Specific size and the current distribution of electrode have relevant uniformity. The magism of biological anization is even basically, magic field reaches the deeply layer anization of anism very easily on toad through skin and skeleton. The magic stimulation does not have wound. The resistance rate of skin and skeleton is current and anization resistance bee inve
