Electrocardiography and Magnetocardiography Today

  • Pierre Rijlant


The recent developments of magnetocardiography have provided the basis for a valid confrontation of electro-cardiograms and mag-netocardiograms. The general tendency is to emphasize the similarity of both recordings, both originating from the same electrical generator system. In his 1979 review, Geselowitz although considering the configuration of the magnetocardiogram’s waveform to be much the same as that of the electrocardiogram, also signals the great clinical potential interest in the measurements of currents of injury by magnetocardiography as performed already in the dog’s heart and evokes the influence of the movements of the blood on the external magnetic field. This component of the magnetic field, not related to the activation process of the heart, was considered in 1980 at the Paris meeting of the 8th European Congress of Cardiology. A quantitative appraisal of the magnetic signals related to the movements of the heart and of the blood was attempted by Norman Tepley who analyses the component of the magnetic field that is proportional to the ambient field and arises from the presence of diamagnetic blood and tissue. This also makes for the possibility to detect the blood flow in the aorta and in the large arteries.
