心脏起搏器应用于临床已有半个世纪的历史,曾使无数症状性心跳过缓患者的生活质量得到了改善,也避免了不少心脏停跳事件的发生,它为人类健康作出了公认的贡献。现就心脏起搏器谈谈以下几方面的问题: 一、心脏起搏器。心脏起搏器是工程技术人员应用电子计算机技术和生物医学工程技术发明的一种微型“心脏助跳”装置,它以锂——碘电池为能源,可以持续工作十多年。起搏器凭借其中微型电脑测知病人的心跳,当病人心跳慢于其设置的频率时起搏器发挥助跳功能,以保持心跳不低于设置频率;当病人自身心跳增快时,起搏器自动启闭。频率设置为通过体外程控实现。起搏器的整体重量32克至18.5克,体积相当于一般中号手表大小。
The history of half a century of clinical use of pacemakers has led to an improvement in the quality of life of many patients with symptomatic bradycardia and the avoidance of a number of cardiac arrest events that have made human health recognized Contributions. Now on the pacemakers to talk about the following aspects: First, the pacemaker. Pacemaker is a miniature “heartbeat” device invented by engineers and technicians using computer technology and biomedical engineering technology. It can work continuously for over ten years with lithium-iodine battery as its energy source. Pacemakers with which the microcomputer detects the patient’s heartbeat, when the patient’s heart beat slower than the frequency set when the pacemaker play aiding function to keep the heart rate not less than the set frequency; when the patient’s own heart rate is increased, pacing Automatic opening and closing device. The frequency is set to be programmed by in vitro program. The overall weight of the pacemaker 32 grams to 18.5 grams, the size is equivalent to the average size of medium watches.
