Clinical trials with one type of lithium pacemaker generator. 1978

W G Trapp, and C A Taunton

Cardiac Pacemakers, Inc. (CPI) solid-state, lithium-powered pulse generators were implanted in 100 patients by one surgeon in a twenty-eight-month period. Eleven CPI pacer generators were replaced, none due to pacer failure. Ninety-nine percent of the patients were followed for a total of 1,397.55 patient-months; 12 patients died, but no deaths appeared to be pacemaker related. The average age of the patients at the time of implantation was 72.8 years. If the warranty period of six years is achieved, the number of pacemaker generator changes required by many of the patients in this group could foreseeably be zero.
