摘　　要：DDD型起搏可提供生理性心脏功能,但常可因出现房颤(或心房电极移位)而失去心房的作用。窦结变速不全的患者,则 DDD 型起搏不能随运动而增加起搏率。VVIR型起搏虽可使心室起搏率随患者活动量的增加而加快,但缺乏房室同步功能。最新发展起来的DDDR型起搏可同时获得房室同步及频率应变的理想功能。本文结合18例DDD、4例VVIR及2例DDDR型起搏的应用经验,认为(1)DDDR型起搏对人体肌肉活动反应快且房室起搏率的加速很接近生理需要;(2)当今选用最合乎不同心律失常患者需要的更具有生理功能的起搏器变为更重要了。DDD pacing was considered as a“physiological pacing”in the past;however,atrial contribution was lost once the atrial fibrillation(or dislogement of atrial lead)occurred.In patients with chronotropic incompetence of the sinus node,the DDD pa-cing won't provide rate response.In VVIR pacing mode,though the ventricular pacingrate accelerates during physical stress,this causes loss of AV synchrony.The newlydeveloped DDDR pacing system provides the most physiological function to main-tain AV synchrony and rate response simultaneously.Based on the experience with4 cases of VVIR pacing and 2 cases of DDDR pacing and our earlier report of DDDpacing in 18 cases,we conclude that(1)the response time of DDDR pacing to bodymuscle activity is rapid and the acceleration of AV sequential pacing with activityis somewhat physiological;and(2)selecting a more physiological pacemaker for apatient's arrhythmia type becomes more important today.
