Abstract
An implantable pulse generator senses a cardiac signal, identifies cardiac events in the cardiac signal, and starts a blanking interval including a repeatable noise window blanking interval in response to each cardiac event. When noise is detected during the repeatable noise window blanking interval, the noise window blanking interval is repeated. In one embodiment, 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 until the noise ceases. Alternatively, when the sum is greater than the pacing escape interval, the pace escape interval is repeated.
