Patent ID: 6856832

Claim:
A biological signal detection system comprising: a first electrode group comprising a pair of first electrodes adapted to be located at first positions in the vicinity of an upper end of a sternum of a patient, for detecting a first biological signal; a first support, adapted to be attached to living tissue, for supporting said first electrode group such that a distance between the first electrodes is fixed; a second electrode group comprising a pair of second electrodes adapted to be located at second positions at which a CM 5 lead and a NASA lead are established between the first electrodes and the second electrodes, for detecting a second biological signal; and a transmitter comprising: an electric circuit for processing the first biological signal and the second biological signal to generate the CM 5 lead, the NASA lead, and telemetering signals to be transmitted; a first connection section for electrically connecting the first electrodes to said transmitter via the first support; and a second connection section for electrically connecting the second electrodes to said transmitter such that a distance between each of the second electrodes and the first electrodes is variable.
