摘要： An atrial event and a ventricular event can be received, and an atrioventricular (AV) delay can be provided using information about the atrial and ventricular events. The AV delay can be increased after a first condition is satisfied to allow a heart to regain intrinsic control of ventricular activation, and changed after a second condition is satisfied to allow the heart to remain in intrinsic control of ventricular activation.

摘要： An implantable pulse generator and a method of operation, where the pulse generator is adapted to sense at least a first cardiac signal. Cardiac events are identified in the first cardiac signal, in response to which a blanking interval is started. The blanking interval includes a repeatable noise window blanking interval. When noise is detected during the repeatable noise window blanking interval, the noise window blanking interval is repeated. Depending upon the type of sensed cardiac event (paced or intrinsic) the blanking interval is adjusted to either to a first overall duration or a second overall duration. The second overall duration includes a first timed interval that has a programmable value. The repeatable noise window blanking interval starts after the first timed interval of the second overall duration. The duration of repeated repeatable noise window blanking intervals is summed and compared to a pacing escape interval. When the sum is greater than the pacing escape interval, asynchronous pacing pulses are delivered. When the noise ceases, so does the delivery of asynchronous pacing pulses. Alternatively, when the sum is greater than the pacing escape interval, the pace escape interval is repeated. Pacing is resumed after one pacing escape interval after the noise signal ceases.
摘要翻译：一种可植入脉冲发生器和操作方法，其中所述脉冲发生器适于感测至少第一心脏信号。心脏事件在第一心脏信号中被识别，响应于此，开始消隐间隔。消隐间隔包括可重复的噪声窗消隐间隔。当在可重复的噪声窗消隐间隔期间检测到噪声时，重复噪声窗消隐间隔。取决于感测的心脏事件的类型（起搏或内在的），消隐间隔被调整到第一整体持续时间或第二总持续时间。第二总持续时间包括具有可编程值的第一定时间隔。可重复的噪声窗消隐间隔在第二个总持续时间的第一个定时间隔之后开始。将重复的可重复噪声窗口消隐间隔的持续时间相加并与起搏逃逸间隔进行比较。当和大于起搏逃逸间隔时，异步起搏脉冲被传递。当噪声停止时，异步起搏脉冲的传递也是如此。或者，当总和大于起搏逃逸间隔时，重复起搏逃逸间隔。在噪声信号停止后，起搏间隔恢复一段起搏。
