ABSTRACT:
Methods and apparatus are provided for alleviating the effects of crosstalk in an implantable stimulation device. An autoblanking approach is provided whereby the total blanking interval is made up of an absolute blanking interval followed by a retriggerable relative blanking interval. The implantable stimulation device sensing circuitry is disabled during the absolute blanking interval and enabled during the relative blanking intervals. If a signal is detected during a relative blanking interval, a successive relative blanking interval is initiated. If no signal is detected, then relative blanking terminates. Further, an approach for combining safety standby pacing with autoblanking is provided. If autoblanking terminates before the crosstalk sensing interval reaches a maximum blanking interval, then safety standby pacing is cancelled. Another aspect of the invention relates to monitoring the amount of time in a safety standby sensing window during which signals are detected. If signals are detected longer than a predetermined time, then a safety standby stimulation pulse is provided, otherwise, safety standby pacing is inhibited.
