ABSTRACT:
A process of regulating by an extra-corporeal control unit an implanted cardiac stimulator comprising a pulse generator and a pair of electrodes, comprises controlling the stimulator so that it functions at a fixed rhythm independent of normal cardiac rhythm and detecting by the extra-corporeal unit successive pulses emitted by the stimulator. After each of selected stimulator pulses detected, and during the whole period between successive stimulator pulses, a train of successive control pulses is transmitted by the control unit and is received by the stimulator as binary information "1". On the contrary, no train of successive control pulses is transmitted during the whole period between other successive stimulator pulses and this is received as binary information "0". The binary information thus received is used to regulate the operation of the stimulator. The extra-corporeal unit displays the pulses emitted by the stimulator to verify that the regulator is effective.
