[Recording of the cardiac magnetic field. Technical considerations and initial results in hospital practice].
Recording the magnetic field of the heart poses enormous technical problems. Whatever type of captor is used, the parasite magnetic fields are 11000x more powerful than those of cardiac origin, and must be excluded. It is for this reason that magnetocardiography has remained a laboratory technique until the last few years. The authors present an induction magnetocardiograph whose specifications make it suitable for use in hospital practice. Thanks to the selectivity of the captor, it is possible to produce magnetic plots of the thorax.
