自从第一例人工心脏起搏器用于临床以来,各种类型的起搏器不断出现并陆续应用于临床。近年来比较盛行的一个概念就是非心房同步的生理按需起搏,目前已有各种频率应答型起搏器进入临床使用,但目前大多只用单参数来控制起搏频率,为了更逼真地模仿自然的心率变化就必须采用多参数进行心率的调节。本文提出了一种用呼吸率和体温两个参数控制起搏频率的新方法并介绍了在各领域已广泛应用的模数控制理论在多参数频率应答式起搏系统中的应用。模糊控制的一个特点就是其控制程序的表达方式,它是用语言来描述控制程序而不是用方程或曲线进行控制,因此医生可以方便地选择控制程序,用语
Since the first artificial heart pacemakers have been used clinically, various types of pacemakers have appeared and are being used clinically. One of the more prevalent concepts in recent years is that non-atrial synchronized physiological on-demand pacing, there are a variety of frequency response pacemaker into clinical use, but most currently only use a single parameter to control the pacing frequency, in order to be more realistic To mimic the change of heart rate must use multiple parameters for heart rate adjustment. In this paper, we propose a new method to control the pacing frequency with two parameters of respiration rate and body temperature and introduce the application of the modulus control theory that has been widely used in various fields in the multi-parameter frequency response pacing system. One of the features of fuzzy control is the way in which the control program is expressed. It describes the control program in terms of language rather than the equations or curves so the doctor can easily choose the control program.
