SENSOR DEVICE FOR ELECTROCARDIOGRAM

摘要

The sensor device is intended to be implemented at the vicinity or inside a nuclear magnetic resonance apparatus, and more particularly on a patient inside the canal of the magnet of a magnetic resonance imager (MRI), characterized in that it is essentially comprised of, on the one hand, at least two non-metal electrodes (1) intended to be applied to the skin of a patient (2), and on the other hand, of an electro-optical conversion, amplification and filtering module (3) for the electric signals received from the heart by means of the electrodes (1), said module being arranged in a shielded casing (4) forming a Faraday cage, and optically connected to a display and/or monitoring apparatus and, finally, comprising a support body (6) made of non-magnetic material, carrying the electrode (1) and the shielded casing (4) containing the module (3).
