自1990年以来,我院按照埋藏人工心脏起搏器的工作规程(孙瑞龙,安装埋藏起搏器工作规程.起搏与心脏,1991,1∶50),结合本院条件因陋就简埋藏永久性人工心脏起搏器14例,男10例,女4例,年龄28～86(平均49.4)岁。冠心病8例,其中1例合并糖尿病,1例合并胸骨后甲状腺肿,心肌病4例,特发性病态窦房结综合征2例。Ⅲ度房室传导阻滞(AVB)6例。Ⅱ度Ⅱ型AVB 3例,慢-快综合征3例,严重窦性心动过缓2例。所用起搏器为秦明公司Pinnacle 8619型单极(VVIM)起搏器13只,Polaris 9051型单极(VVI)起搏器1只。 (1)用按需型临时人工心脏起搏器代替起搏分析仪为了把电极置于理想的位置,要选择一个起搏阈值最低的点。采取的方法将临时人工心脏起搏器(上海产)感知灵敏度调至3V,幅度调至10V,以按需工作方法开始起搏,持续5～10分钟,观察无不
Since 1990, our hospital in accordance with the working procedures buried artificial heart pacemaker (Sun Ruilong, the installation of pacemaker working procedures. Pacing and the heart, 1991,150), combined with the conditions of our hospital due to the simple buried permanent artificial heart Pacemakers in 14 cases, 10 males and 4 females, aged 28 to 86 (mean 49.4) years of age. Coronary heart disease in 8 cases, including 1 case of diabetes mellitus, 1 case of post-sternal goiter, cardiomyopathy in 4 cases, idiopathic sick sinus syndrome in 2 cases. Ⅲ degree atrioventricular block (AVB) in 6 cases. Ⅱ degree Ⅱ AVB in 3 cases, slow-fast syndrome in 3 cases, severe sinus bradycardia in 2 cases. The pacemakers used were 13 Pinnacle 8619 single-pole (VVIM) pacemakers and 1 Polaris 9051-type monopolar (VVI) pacemaker. (1) Replacement of the pacing analyzer with on-demand temporary artificial pacemaker In order to put the electrode in the desired position, a point with the lowest pacing threshold is selected. Method to be taken temporary artificial cardiac pacemaker (Shanghai production) sensitivity sensitivity adjusted to 3V, amplitude adjusted to 10V, to start working on demand pacing for 5 to 10 minutes to observe all
