Forty-five patients aged 80 years or older at the time of initial permanent pacemaker implantation were followed for 3 to 132 months (mean 40.8). There were 27 males and 18 females. The mean age was 84 years. Acute voltage threshold, lead impedance, R wave amplitude of these patients showed no difference from those of younger patients (< 80 years). Complications occurred in 5 patients as follows: cerebral infarction, 3: perforation, 1; lead displacement, 1. Ten patients died, and main causes of death were decrepitude and cancer. The five-year cumulative survival rate (75.9%) was superior to the expected survival rate (65.8%) by life-table analysis. In conclusion, pacemaker therapy for elderly patients is safe, and seemed to improve their long-term prognosis.
45例初次植入永久性起搏器时年龄在80岁及以上的患者接受了3至132个月的随访（平均40.8个月）。其中男性27例，女性18例。平均年龄为84岁。这些患者的急性电压阈值、导线阻抗、R波振幅与年轻患者（<80岁）相比无差异。5例患者出现并发症，情况如下：脑梗死3例；穿孔1例；导线移位1例。10例患者死亡，主要死亡原因是衰老和癌症。通过寿命表分析，五年累积生存率（75.9%）高于预期生存率（65.8%）。总之，老年患者的起搏器治疗是安全的，似乎可以改善他们的长期预后。
