埋藏式起搏器的出现,使一大类致命的心律失常患者能依靠起搏器而得到长期有效的治疗.20年来发展很快,安装人数由60年代初的1～2千人/年发展到去年的25万人/年,在美国每百万居民中平均已有1500人依赖起搏器而生活.促使它发展的主要原因是用起搏治疗患有高度房室传导阻滞、有症状的心动过缓及病窦综合症的患者能延长病员的寿命,降低猝死率和提高生活质量;其次是起搏技术上的进步使起搏器的安装简便、安全,易于为人们所接受.
The emergence of a buried pacemaker has led to a long-term and effective treatment of a large group of fatal cardiac arrhythmias by pacemakers, which has developed rapidly in 20 years and has been installed by 1,2,000 people per year in the early 1960s As of last year’s 250,000 people / year, an average of 1,500 people per million inhabitants of the United States rely on pacemakers for living.Primary reasons for its development are palliative treatment of patients with a high degree of atrioventricular block, symptomatic Of patients with bradycardia and sick sinus syndrome can extend the patient’s life expectancy, reduce the rate of sudden death and improve quality of life; followed by advances in pacemaker technology makes the pacemaker installation easy, safe and easy to be accepted.
