摘要： A pacing protocol is provided that reduces or minimizes ventricular pacing in favor of intrinsic conduction. When operating in a mode that provides ventricular pacing, a series of conduction checks are performed to determine if intrinsic conduction has returned. These conduction checks occur according to a predetermined pattern that generally includes longer intervals between subsequent attempts. The AV interval provided for dual chamber based pacing is modulated and generally moves from a larger value to a nominal value as the interval between unsuccessful conduction checks increases.

摘要： A pacing protocol is provided that reduces or minimizes ventricular pacing in favor of intrinsic conduction. When operating in a mode that provides ventricular pacing, a series of conduction checks are performed to determine if intrinsic conduction has returned. These conduction checks occur according to a predetermined pattern that general includes longer intervals between subsequent attempts. A maximum interval is provided such that conduction checks are not repeated sequentially at the same time of day when at this maximum interval.

摘要： An implantable cardiac pacing device delivering minimum ventricular pacing and an associated method control intervals timed by the device during sensing and pacing. An atrial-only pacing mode is set in response to sensing intrinsic ventricular events in the ventricular chamber. A first post-ventricular atrial refractory period is set following each of a plurality of ventricular events sensed in the ventricular chamber, and atrial events each being sensed during first post-ventricular atrial refractory periods are detected. A second post-ventricular atrial refractory period is set in response to detecting the atrial events each being sensed during the first post-ventricular atrial refractory period.

摘要： A system and method is provided for reliably indicating that an implantable medical device is in need of replacement. An implantable medical device includes a battery and a replacement indicator timer. The battery provides power to the implantable medical device. The replacement indicator timer counts a replacement time period to a determined replacement date for the implantable medical device. The replacement indicator timer starts the counting when an operational characteristic of the battery reaches a selected value.

摘要： A feature named "atrial tracking recovery" (ATR) provides a means of restoring delivery of cardiac pacing therapy upon identification of an AR-VS pattern of cardiac activity. The present invention incorporates a method of monitoring such patterns to determine if they are terminable. Once the AR-VS pattern is identified, according to the present invention the PVARP is shortened to allow sensing of the atrial event, which previously was unable to initiate an SAV interval. Subsequent SAV intervals are shortened until an atrial event is sensed so that a ventricular pacing stimulus is delivered after the SAV interval expires. Since the SAV interval is normally programmed to an interval that is shorter than the intrinsic conduction time, ventricular pacing stimulus is provided after the SAV ends, thereby effectively restoring delivery of a ventricular pacing modality such as cardiac resynchronization therapy (CRT).
摘要翻译：称为“心房跟踪恢复”（ATR）的特征提供了在识别心脏活动的AR-VS模式时恢复心脏起搏治疗递送的方法。本发明包括监视这些模式以确定它们是否可终止的方法。一旦AR-VS模式被识别，根据本发明，PVARP被缩短以允许感测心房事件，其先前不能发起SAV间隔。随后的SAV间隔被缩短直到心房事件被感测到，使得在SAV间隔期满之后输出心室起搏刺激。由于SAV间隔通常被编程为短于内在传导时间的间隔，所以在SAV结束之后提供心室起搏刺激，从而有效地恢复心室再同步治疗（CRT）之类的心室起搏模式的传递。
