About the Marker Channel
™
Diagram
The Marker Channel Diagram (see example below) shows more details of
pacemaker operation by depicting the various timing intervals, including
blanking and refractory periods. The diagram is intended to further clarify
operation of the pacemaker and simplify analysis of the patient’s ECG.
NOTE: If events portrayed on the diagram occur in very rapid succession,
the Pace and Sense marker annotations (P, S, R) may not appear, and the
supplemental labels (Act., Safe, PVC, and NCAP) that define certain
events may overlap. Overlapping characters or labels displayed on the
screen may not appear exactly the same on the printout.
NOTE: In situations where the event rate is unusually high, the Marker
Channel Diagram may be less than 10 seconds in length due to processing
limitations.
