If an error message appears, you should reposition the programming
head and freeze another 10-second trace segment to obtain a new Marker
Channel Diagram.
NOTE: A Marker Channel Diagram cannot be displayed if an interroga-
tion or programming transmission occurred during the 10-second interval
of the frozen trace.
Below is an explanation of the messages that indicate an error condition.
“Missing Event” — This message appears if an event did not occur when it
was expected based on the interrogated data registered in programmer
memory. This situation can occur in the presence of interference that
interrupts telemetry.
Interruption of the diagram followed by the appearance of a Threshold
Margin Test (pacing at 100 ppm for three cycles) indicates that movement
of the programming head during recording of the 10-second frozen trace
opened and closed the pacemaker reed switch. In this situation, the Thresh-
old Margin Test depicted on the diagram may be accompanied by one or
more “Missing Event” messages.
“Diagram Error” — This message indicates that a particular sequence of
events portrayed by the Marker trace cannot be processed and properly
displayed by the Marker Channel Diagram.
“Bad Data” — This message indicates that the programmer has not
received the information it requires to complete the Marker Channel
Diagram. This can occur when there is an interruption or fault in the
telemetry being received - possibly due to interference or movement of the
programming head.
