埋藏式心脏起搏器在我国已得到了较广泛的使用,但起搏频率均不能按生理要求作出响应,因此其性能有一定的局限性,需进一步提高。众所周知,心功能正常者的心率随身体需氧量改变。人体运动,氧耗增加时,心率应随之上升,以适应机体运动的需要。但目前起搏器病人只好通过限制自身活动来被动适应予置的起搏频率。鉴于这一问题,我们进行了运动型自适应起搏器的研究,使起搏频率能随人体的运动量变化,现已取得了一点初步成果。 Buried cardiac pacemaker has been widely used in our country, but the pacing frequency can not respond to physiological requirements, so its performance has some limitations, need to be further improved. As we all know, normal heart rate with the body’s oxygen demand changes. Human body movement, oxygen consumption increases, the heart rate should rise, in order to adapt to the needs of body movement. However, the current pacemaker patients had to passively limit their own activities to adapt to the pace of pacing. In view of this issue, we conducted a study of exercise-based adaptive pacemaker, so that the pacing rate with the body’s movement changes, and now has made some initial results.
