Between January 1974 and December 1976, 470 mercury-cell pacemakers and 353 lithium-cell pacemakers were implanted at Surgical Clinic A of the University Hospital of Zurich. Within the first 24 months 15.5% of the mercury-cell pacemakers had to be exchanged because of premature battery depletion and 1.3% due to dysfunction of electronic components. None of the lithium-cell pacemakers had to be removed for these reasons. In 6 lithium-cell pacemakers, however, overhaul was necessary because of sensing failure. One unit had to be removed after one year for local decubitus. In two cases, repositioning of the batteries was necessary because of local muscle stimulation.
1974年1月至1976年12月期间，苏黎世大学医院外科诊所A植入了470个汞电池起搏器和353个锂电池起搏器。在最初的24个月内，15.5%的汞电池起搏器因电池过早耗尽而不得不更换，1.3%因电子元件功能障碍而更换。锂电池起搏器无一因这些原因而必须取出。然而，有6个锂电池起搏器因感知故障而需要大修。有1个装置在一年后因局部褥疮而必须取出。在两例病例中，由于局部肌肉刺激，需要重新定位电池。
