摘要
目的：探讨人工心脏起搏器（ＰＭ）植换方式选择。方法：起搏器植换２２例；其中，能源耗竭１４例，感知和起搏功能障碍４例，囊袋感染破溃致ＰＭ外露４例。非感染者起搏阈值（ＰＴ）＜２．５Ｖ，行原位植换；ＰＴ值＞３．０Ｖ或有感染者，更换全套起搏系统。结果：非感染的１８例中，１０例ＰＴ值＜２．５Ｖ，实行原位植换；８例ＰＴ值＞３．０Ｖ和其余４例有感染者，植入新的起搏系统。术后随访１～４年，ＰＭ工作均正常。结论：ＰＴ值的大小是选择ＰＭ植换方式的重要指标之一。
Objective:To study the methods used for reimplantation of artificial cardiac pacemaker.Methods:Reimplantation was performed in 22 patients,14 with power source depletion,4 with failure of function and 4 with breaking of pacemaker packing.In non infected patients with pacing threshold(PT) value<2.5 V,reimplantation of pacemaker was made in the original site.In patients infected or with PT value>3.0 V,reimplantation of a new pacemaker system was made in another site.Results:After reimplantation,all patients were followed up from 1 to 4 years,pacemakers were working normally.Conclusions:PT value is an important factor in selection of the method of reimplantation of pacemaker.
