由于人工心脏起搏术在治疗心率过缓和心律失常等严重威胁人类生命的心脏疾患中,具有显著而又不能完全被其它治疗方法代替的效果,因此这一技术日益受到世界各国的重视。我国研制人工心脏起搏器已近20年的历史,体内埋藏式起搏器用于临床迄今亦有10余年了。据统计,我国体外心脏起搏器生产量的总和已达9000台,其中具有超速抑制功能的按需型起搏器约占80%,目 Because artificial heart pacing has obvious and can not be completely replaced by other therapies in the treatment of heart diseases such as arrhythmia and heart rate, which are serious threats to human life, this technique is increasingly valued by all the countries in the world. The development of artificial pacemaker in our country has been nearly 20 years. There are more than 10 years of clinical application of buried pacemaker in our country. According to statistics, China’s total output of cardiac pacemakers in vitro has reached 9,000 units, of which on-demand pacemaker with speeding inhibition of about 80%, head
