人工心脏起搏系统由脉冲发生器、起搏电极导线两部分组成。起搏系统植入人体后,电极导线的破损及折断的发生率较高,发生时需要植入新的电极导线,不仅增加了患者手术次数和住院率,还增加了起搏系统的感染率。近年来,无电极导线心脏起搏器已问世,预计2015年投入临床使用。该起搏器外观就像是一枚消炎痛栓,长2.4cm,直径20F,整体容积0.75ml(图A)。起搏的阴、阳极位于头、尾两端,相距1.7cm(图B),其头部4根金属丝可螺旋倒钩而主动固定起搏器。经起搏器释放系统从周围静脉到达预定部位后(图C),先测试阈值,符合要求后,推送固定起
Artificial heart pacing system consists of pulse generator, pacing lead wire two parts. Pacemakers implanted in the human body, the electrode lead breakage and fracture of the higher incidence of occurrence of the need to implant a new electrode lead, not only increased the number of patients with surgery and hospitalization, but also increased the rate of infection of the pacing system. In recent years, electrodeless cardiac pacemakers have been released and are expected to be put into clinical use in 2015. The pacemaker looks like an indomethacin suppository with a length of 2.4 cm and a diameter of 20 F with an overall volume of 0.75 ml (Figure A). Pace of the anodes, anodes are located in the head and tail ends, separated by 1.7cm (Figure B), the head of the four wires can be spiral barb and take the initiative to fix the pacemaker. After the pacemaker release system from the peripheral vein to reach a predetermined site (Figure C), the first test threshold, meet the requirements, push fixed
