What does 'intermittent p wave trend although stable' mean on a ppm device report?

Sinus node dysfuncti: Considerations regarding atrio-ventricular (A-V) block. A-V block can occur at different levels in the conduction system: above, within and below the His bundle, often with different outcomes. In complete heart block, a PPM should be considered, even when the ventricular response is > 40 beats per minute, since this numerical value was not derived from clinical trial data.
