Abstract :
By studying the chaos attractor of cardiac magnetic induction strength Bz generated by the electrical activity of the heart, we found that its projection in the reconstructed phase space has a similar shape with the map of the total current dipole vector. It is worth noting that the map of the total current dipole vector is computed with MCG recordings measured at 36 locations, whereas the chaos attractor of Bz is generated by only one cardiac magnetic field recordings on the measured plan. We discuss only two subjects of different ages in this paper
