Abstract:
1. An implantable pulse generator, comprising: a signal sensor configured to sense a first cardiac signal and a second cardiac signal; a pace output circuit configured to deliver pacing pulses; a blanking window initiator coupled to the signal sensor and the pace output circuit, the blanking window initiator configured to identify cardiac events, start a blanking interval in response to each event of the cardiac events being identified in the first cardiac signal or the second cardiac signal, the blanking interval including a repeatable noise window blanking interval, and adjust the blanking interval depending on which of the first cardiac signal and the second cardiac signal the each event is identified in and depending on whether the each event is identified as a paced cardiac event or a sensed cardiac event; and a noise detector coupled to the signal sensor and the blanking window initiator, the noise detector configured to detect noise in the first cardiac signal and the second cardiac signal during the repeatable noise window blanking interval, wherein the blanking window initiator is configured to repeat the repeatable noise window blanking interval in response to the noise being detected in the first cardiac signal or the second cardiac signal during the repeatable noise window blanking interval.
