For the past 4 years, we have used highly efficient Medtronic electrodes (Nos. 6901 and 6907), with small surface areas, for cardiac pacemakers. We have found that chronic thresholds average 1.6 Ma. at a 1 msec. pulse duration, compared to 4.9 Ma. fo

In a study of the electrical stimulation threshold behavior of electrodes in long-term ventricular pacing, 120 patients were followed up for a minimum of 5 years after initial pacemaker implantation (range 5 to 11.3 years). In each patient, at least

During cardiac pacemaker implantation and pulse generator replacement, unipolar, right ventricular electrograms were recorded from 133 patients (77 at implantation and 56 at pulse generator replacement) at 200 mm. per second with a band pass of 0.1 t

In order to evaluate the behavior of lithium-powered cardiac pacemakers, a database of 25,919 lithium-powered pacing systems including 23,517 single and 2,402 dual chambered pacemaker generators were followed in 21,750 patients. Of this group, 11,319

Of over 10,000 lithium-powered pacemakers followed by a commercial franstelephone monitoring service, 148 have been explanted due to rate decline. A breakdown according to the power cell manufacturers shows that the longevity is not uniform, indicati

Clinical studies of the threshold of endocardial cardiac stimulation were carried out as part of a therapeutic cardiac pacing effort over a period of 8 yrs., and included a total of 256 electrode measurements, 76 chronically after at least 6 months a
