自从 195 8年第一台心脏起搏器在美国诞生之后 ,经过 4 0余年的不断改进 ,目前起搏器的程控参数已达 2 0多项 ,为适应不同患者不同时期的生理需要提供了极大的余地 ,为了使起搏器更符合患者的需要 ,并充分地利用起搏器的潜在功能 ,要求医生熟知起搏器性质 ,最大限度地利用参数? Since the birth of the first pacemaker in 1958 in the United States, after more than 40 years of continuous improvement, the program-controlled parameters of pacemaker have reached more than 20 at present. In order to meet the physiological needs of different patients in different periods, In a large area, in order to make the pacemaker more suitable for patients’ needs and make full use of the potential functions of the pacemaker, doctors are required to be familiar with the nature of the pacemaker and make maximum use of the parameters.
