IMPROVEMENT IN IMPLANTATIONS FOR CARDIAC STIMULATION BY PACEMAKER

摘要

Implantation for cardiac stimulation by pacemaker including also a radio-frequency receiver (14) for alternative cardiac stimulation by means of an external pacemaker and a radio-frequency transmitter; wherein the radio-frequency receiver (14) is not equipped with the usual plate in contact with the patient's tissues and is clamped on a bipolar electrode (12) connecting the pacemaker to the heart. In this way, the stimulating signals either from the pacemaker (10) or, in alternative, from the external transmitter, are transmitted through this electrode (12), being the pacemaker (10) also insulated and without the external plate in contact with the patient's tissue. As a modification wherein the pacemaker is equipped with the plate in contact with the patient's tissue, the electrode length connecting the pacemaker with the radio-frequency receiver is unipolar while the length of electrode connecting the radio-frequency receiver to the heart remains bipolar.
