    • A preferred atrial-based pacing method and apparatus is provided using an intelligent cardiac pacing system to having the ability to continue atrial-based pacing as long as relatively reliable AV conduction is present. In the event that such relatively reliable AV conduction is not present, mode switching to a DDD/R or a DDI/R pacing mode while continually biased to mode switch back to atrial-based pacing. The standard or relatively reliable AV conduction may be changed either automatically or manually. This increases pacing that utilizes natural AV conduction however possible so as to gain all the benefits of cardiac contractile properties resulting therefrom, while tolerating the occasional missed ventricular depolarization (i.e., non-conducted P-wave). In the event where relatively reliable AV conduction is not present, the pacing mode is switched to a DDD/R mode while detecting a return of the relatively reliable AV conduction (and resulting mode switch to preferred atrial based pacing).
    • 只要存在相对可靠的AV传导,使用智能心脏起搏系统提供优选的基于心房的起搏方法和装置,以具有继续心房起搏的能力。 在不存在这种相对可靠的AV传导的情况下,模式切换到DDD / R或DDI / R起搏模式,同时不断偏向模式切换回基于心房的起搏。 标准或相对可靠的AV传导可以自动或手动改变。 这增加了使用自然AV传导的起搏,尽可能地获得心脏收缩性质的所有益处,同时容忍偶尔的心室去极化(即,未传导的P波)。 在不存在相对可靠的AV导通的情况下,起搏模式被切换到DDD / R模式,同时检测到相对可靠的AV导通的返回(并且导致的模式切换到优选的心房起搏)。
