Pacemaker Detection
Pacemaker detection for the DigiTrak XT recorder is automatically defaulted to OFF. You
must turn it On for each procedure in which it is used or save the setting as part of the default
settings.
Pacemaker Threshold
The DigiTrak XT recorder allows the user to adjust the threshold for pacemaker spike
detection. The purpose of this feature is to raise or lower the threshold of the recorder
detection in order to eliminate spikes from a rate-modulated pacemaker or lower the threshold
to allow for better detection of bipolar pacemakers.
NOTE Adjusting the threshold on the DigiTrak XT recorder does NOT affect any threshold settings on the
patient’s pacemaker. The adjusting of the threshold settings are confined totally to the function of the
recorder.
You do not have to adjust the pacemaker recording threshold for all recordings.
Adjusting Pacemaker Thresholds
To adjust a pacemaker threshold
1

2 Ensure that the Pacer Detector setting is ON.
3 While viewing the ECG waveform, press Enter to display the pacemaker threshold
indicator on the right side of the screen.
The top position of the bar indicates maximum sensitivity. The indicator defaults to one
below the maximum sensitivity.
