The dislodgement rate of endocardially placed pacemaker leads can be decreased by the use of special-type electrodes. Since 1963 a total of 2100 pacemaker implantations was performed. Since 1970 we have been using special-type electrodes in 15 to 20% of our patients each year. The complication rate of all pacemaker leads implanted in the period 1974 to 1978 was 7.6%, the rate of the special type electrodes alone came up to 15%. The lead IE--65--I had the greatest deal of this - 11 out of 43 leads had to be removed. 152 electrodes type IVE--85--armed with metal hooks - were implanted, 18 of which had to be revised and 17 of 117 rigid leads type IE--60--KS--10 revealed failure which made revision necessary. In contrast, 54 screw-in leads type 6957, Medtronik and AE--60--YR, Biotronik caused only one perforation - a lethal one. Primary experiences with a porous tip lead (CPII--4116) are good enough to recommend the use of this electrode as a lead of first choice. We saw 2 dislodgements in 50 implantations. Failure to sense or to pace were never seen (time of observation 2 to 18 months).
使用特殊类型的电极可降低心内膜植入起搏器导线的脱位率。自1963年以来，共进行了2100例起搏器植入手术。自1970年以来，我们每年在15%至20%的患者中使用特殊类型的电极。1974年至1978年期间植入的所有起搏器导线的并发症发生率为7.6%，仅特殊类型电极的发生率就高达15%。IE-65-I型导线的情况最为严重——43根导线中有11根不得不取出。植入了152根带有金属钩的IVE-85型电极，其中18根需要修正，117根IE-60-KS-10型刚性导线中有17根出现故障需要修正。相比之下，54根美敦力6957型和百多力AE-60-YR型旋入式导线仅导致1例穿孔——致命穿孔。多孔尖端导线（CPII-4116）的初步经验足以推荐将这种电极作为首选导线。我们在50例植入手术中观察到2例脱位。未出现感知或起搏失败（观察时间为2至18个月）。
