An argument for pacemaker reuse: pacemaker mortality in 169 patients over ten years.

Retrospective examination of 169 consecutive pacemaker patient deaths was done to test the hypothesis that early mortality would preclude full utilization of current battery longevity. We found a 58% mortality within two years of the last generator implant. Nineteen percent occurred within six months, and 38% occurred within a year. This compares to a current clinic of 246 patients where 43% have utilized these pacemakers for greater than 48 months. The age comparison shows that those who died were older than the living controls. The 58% 24-month mortality demonstrates that many patients underutilize expected battery life. The economic implications of pacemaker reuse can then be understood.
