Missing Markers — A programming command or interrogation momen-
tarily interrupts the transmission of Marker Channel telemetry. This inter-
ruption can result in missing markers. The point at which the command
occurred is marked above the ECG trace by a “down” and/or “up” arrow.
The down arrow (
W) indicates a transmitted command from the program-
mer; the up arrow (
V) indicates a telemetry response from the pacemaker.
Displaying Pacing Artifacts
During processing and amplification of the patient’s ECG signal, the pro-
grammer automatically detects and enhances pacing artifact so that they
appear on the ECG display and printout. Under certain conditions, some
types of interference can trigger artifact detection causing false artifacts to
appear on the patient’s ECG.
9790 Programmer
With the 9790 programmer, you can turn the artifact display on or off.
Turning the artifact display off allows you to monitor the patient’s ECG
without the appearance of pacing artifacts. Disabling this function may be
advantageous in the presence of troublesome interference.
For instructions on turning the artifact display on or off, refer to “Setting
the Artifact Display” in Chapter 9. The Artifact Display options are
accessible via the [
SETUP
...
] button on the Automatic Model Select screen.
NOTE: With the artifact display turned off, pacing artifacts will not show
on the programmer ECG display or printout. Once you turn the artifact
display off, it will remain off until you repeat the procedure to turn it back
on.
