Primary results and follow-up observations in 90 patients with permanent endocardial pacing--covering the period from 1970 to June 1974--are reported. The primary mortality was 3% (3/90), and mortality 4% (4/90). Electrode complications were the most common problem and occurred in 20% implantations. Early or late dislocation of the electrode tip was seen in 12%. With the improved technique is was possible to decrease it significantly through the period. The mean battery life time of Siemens-Elema pacemakers was 26 months. 10% of the failed batteries were replaced urgently. So far the rather high frequency of electrode complications diminishes the advantages of the pacemaker treatment.
本文报告了90例永久性心内膜起搏患者从1970年至1974年6月期间的主要结果及随访观察情况。主要死亡率为3%（3/90），总死亡率为4%（4/90）。电极并发症是最常见的问题，在20%的植入手术中出现。电极尖端早期或晚期脱位的发生率为12%。随着技术的改进，在此期间有可能显著降低该发生率。西门子 - 伊莱玛起搏器的平均电池使用寿命为26个月。10%的电池失效后进行了紧急更换。迄今为止，电极并发症的较高发生率削弱了起搏器治疗的优势。
