1. Electrophysiological analysis system which is intended, in particular for the detection of pathological conditions, characterised in that it includes:

  • a series of electrodes (E1-E6) intended to be placed at various regions of the human body distant from one another,an adjustable DC voltage source (21) which is controlled in order to produce successive waves of a DC voltage which varies from one wave to the other, the duration of the waves being greater than or equal to approximately 0.2 second,a switching circuit (30) designed to selectively connect a pair of so-called active electrodes to the voltage source, and to connect at least one other high-impedance electrode, anda measuring circuit (22, 40) designed to collect data representative of the current in the active electrodes and of the potentials on at least some electrodes connected in high impedance, in response to the application of said waves,and in that, from one wave to the other, the range of voltages covered by the waves is capable of causing the appearance or disappearance of electrochemical phenomena in the vicinity of the active electrodes.
