1. A method comprising:

  • sensing an electrical signal on an implantable medical lead implanted within a chamber of a heart;

    determining whether the sensed electrical signal coincides with a sensed noise signal;

    determining whether the sensed electrical signal occurs during a period of time of an expected intrinsic cardiac signal; and

    triggering delivery of a pacing pulse on the implantable medical lead implanted within the chamber of the heart in which the electrical signal is sensed before expiration of an escape interval associated with the chamber of the heart in which the electrical signal is sensed when the sensed electrical signal coincides with a sensed noise signal and the sensed electrical signal occurs during the period of time of the expected intrinsic cardiac signal.
