1977～1994年底我们对246例患者进行了344次永久心脏起搏器安置术,发生起搏故障50例。男性37例,女性13例,平均年龄57.2±6.3(21～81)岁。临床诊断冠心病28例、病窦综合征11例、特发性传导系统障碍2例、心肌病6例、心肌炎后遗症3例。起搏故障发生与起搏器植入年代的关系见附表。1988年以前我们安置心脏起搏器112例,发生起搏故障45例(40.2%),而1987年后为134例,发生起搏故障5例(3.7%),两者相比有明显统计学意义(P<0.01)。50例起搏故障中,与起搏器工艺水平、电子元件、电池质量及导管电极质量有关者42例(84%),其中40例(95.2%)为国产起搏系统。本组电极脱位14例(5.6%),其中柱状电极1例、翼状电极2例,其余为伞状电极。
From 1977 to the end of 1994, we performed 344 permanent pacemaker placement procedures on 246 patients and 50 pacing failures. There were 37 males and 13 females with an average age of 57.2±6.3 (21-81) years. Clinically diagnosed 28 cases of coronary heart disease, 11 cases of sick sinus syndrome, 2 cases of idiopathic conduction system disorder, 6 cases of cardiomyopathy, 3 cases of myocarditis sequelae. The relationship between the occurrence of pacing failure and the age of pacemaker implantation is shown in the attached table. Before 1988, we placed pacemakers in 112 cases. There were 45 cases (40.2%) of pacing failures, and 134 cases after 1987. There were 5 pacing failures (3.7%). There was statistically significant difference between the two. Significance (P<0.01). Among the 50 pacing failures, 42 (84%) were associated with the pacemaker’s technological level, electronic components, battery quality, and catheter electrode quality, of which 40 (95.2%) were domestically-made pacing systems. The group of electrodes dislocated in 14 cases (5.6%), including 1 case of cylindrical electrodes, 2 cases of alar electrodes, and the rest were umbrella electrodes.
