80年代以来,心房按需起搏(AAI)在国外日益受到重视,国内近3年来也先后在西安、北京、苏州、上海等地开始应用。我院于1992年元月18日、6月4日分别为两名SSS患者成功地安装AAI起搏器,现报道如下。例1,男,39岁,因头晕,胸闷,乏力半年于1991年11月25日入院。ECG示窦缓,心室率40次/min,经窦房结功能测定确诊为病窦,房室交介区传导功能正常,文氏点为130次/min。于1992年元月18日行永久性AAI起搏器埋置术。起搏器为Optima 158C型,经锁骨下静脉送入丁型电极,固定于右心耳,起搏阈值为0.1v,A波振幅为5.0mv。安装起搏器后患者上述症状消失,住院38天出院。例2,男,48岁,因头晕、胸闷,活动后气
Since the 1980s, atrial appetite pacing (AAI) has gained more and more attention abroad. In the past three years, AAI has also been applied in Xi’an, Beijing, Suzhou and Shanghai. Our hospital in January 18, 1992, June 4, respectively, two SSS patients successfully installed AAI pacemaker, are reported below. Example 1, male, 39 years old, was hospitalized on November 25, 1991 due to dizziness, chest tightness and weakness for six months. ECG showed slow sinus, ventricular rate 40 beats / min, the sinus node function was diagnosed as sick sinus, atrioventricular interventricular conduction function is normal, Wen point is 130 beats / min. In January 18, 1992 permanent AAI pacemaker embedding. The pacemaker was Optima Model 158C and was implanted into the D-electrode via the subclavian vein and fixed to the right atrial appendage with a pacing threshold of 0.1 V and a wave amplitude of 5.0 mv. Patient after installing the pacemaker disappeared, hospitalized 38 days discharged. Example 2, male, 48 years old, due to dizziness, chest tightness, activity after the gas
