Abstract
An endocardial pacemaker electrode has a surface region constructed of carbon and having pores for receiving the growth of tissue therein to permit the fixation of the electrode in the atrium or other location by the ingrowth of adjacent tissue. By fixing the location of the electrode, low stimulation thresholds and a consistent magnitude of sensed endocardial signal are maintained.
