频率应答(Rate-responsive)自适应心脏起搏器是近几年来心脏起搏器研究中一比较活跃的分支,它能够根据人体代谢的变化随时自动调节心脏起搏频率,是继全自动型 DDD 起搏器之后出现的符合人体生理需要的一种新型起搏器。频率应答自适应起搏,亦属生理性起搏范畴,它能随着患者生理需求的变化而改变起搏频率,是藉感知和跟踪可作为与心输出量有关的指示的生理变量来完成上述任务 Rate-responsive adaptive pacemaker is a relatively active branch of pacemaker research in recent years. It can automatically adjust the pace of cardiac pacemaker according to the changes of human metabolism. A new type of pacemaker appearing after the pacemaker that meets human physiological needs. Frequency Response Adaptive pacing is also a physiological pacing paradigm that alters the pace of pacing as the patient’s physiological needs change, by sensing and tracking the physiological variables that can be used as an indication of cardiac output task
