<p>Implantation for cardiac stimulation by means of a pacemaker (11) equipped with a rheograph (10) (commercially known as Biorate) also including a radio-frequency receiver (14) for alternative stimulation by means of an external pacemaker and radio-frequency transmitter, the implanted pacemaker (11) and the radio-frequency receiver (14) having a plate (13, 15) in contact with the patient's tissue, the radio-frequency receiver (14) being clamped on a bipolar electrode (12, 12?1A, 121, 121¿B) connecting the implanted pacemaker (11) to the heart (CC); with such arrangement, during the normal stimulation by the implanted pacemaker (11) one polarity (negative) of the stimulation signals is transmitted to the heart through one of the conductors (12, 121) of the electrode while the other polarity (positive) closes through the patient's tissue onto the contact plate (13) of the pacemaker (11); the contact plate (15) of the radio-frequency receiver (14) is connected to the rheograph (10) via the free conductor (121A) of the electrode and acts as one pole of the rheograph (10), being the other pole represented by the pacemaker body (13).</p> |
