ABSTRACT:
The invention relates to a device for the processing of biological signals sampled by electrodes placed on the skin of a patient, having at least two signal measuring electrodes and a reference electrode, an input differential amplifier (10), whose inputs (11,12) are connected to said two electrodes, and a circuit for detecting the absence of the polarization current of said input differential amplifier (10), so as to supply an alarm signal in the case of a detachment or disconnection of at least one electrode.
