一、发展历史永久性埋藏式起搏器临床应用已卅年。随着晶体管、集成电路、锂碘电池以及新的合金和高分子材料的发明,心脏电生理和起搏临床的研究,使埋藏式起搏器的工作寿命延长至5～10年,性能不断完善,可靠性日益提高。现将其主要发展过程概述如下: (1)60年代前期,以心室固定频率式起搏器为主,使用聚乙烯电极导管,以锌汞电池为能源,使用寿命不超过二年。60年代后期至70代中期以心室按需型起搏器为主,解决了心律竞争问题,但仍使用锌汞电池,使用寿命仅20个月左右,使用寿命短成为起搏器应用的主要障碍。 (2)70年代中后期,由于高能长效锂碘
First, the history of development Permanent buried pacemaker clinical application has been years. With the invention of transistors, integrated circuits, lithium-iodine batteries and new alloys and polymer materials, cardiac electrophysiology and clinical study of pacing, the working life of buried pacemakers is extended to 5 to 10 years and performance is continuously improved Increasing reliability. Now the main development process is summarized as follows: (1) the early 60s, the main ventricular fixed frequency pacemaker, the use of polyethylene lead, zinc-mercury batteries for energy, the service life of no more than two years. In the late 1960s to the mid 70s, ventricular-on-demand pacemakers were the main solution to the problem of cardiac arrhythmia, but zinc-mercury batteries were still used with a service life of only about 20 months and short service life as the main obstacle for pacemaker applications . (2) The mid-and late 1970s, due to high-energy long-term lithium iodine
