Abstract
Abstract A portable electrocardiogram recorder is formed from a case containing a device for the digital processing of signals taken by means of at least two electrodes in contact with the skin of the patient. One of the faces of application of said case comprises projecting electrodes in the form of protuberances on said face, said electrodes comprising cavities whose shape is complementary to that of the stud of the usual electrocardiogram electrodes fixed by adhesion to the skin of the patient, thus ensuring both mechanical and electrical coupling, so that said case may be applied either directly to the skin of the patient or indirectly through usual electrodes.
