The AV interval should be considered as a single interval with two subportions. The entire AV interval corresponds to the programmed value, ie, the interval following a paced or sensed atrial beat allowed before a ventricular pacing artifact is delivered. The initial portion of the AV interval is the blanking period. This interval is followed by the crosstalk sensing window.
