Recording a Resting ECG
If you press the Rhythm key after pressing the Stop key, the new report
will either begin printing immediately on the current sheet of paper or
advance to a new page, depending on the setting of the Start rhythm
report on a new page field on the Resting ECG Setup window. Refer to
“Resting ECG Setup” on page 9-6 for details.
ECG Reanalysis
You can reanalyze ECGs if both of the following conditions have been
met:
 Either the Measurement and 12SL Interpretation system option or
the HEART system option is enabled, and
 Reanalysis is selected on the Resting ECG Setup window.
Reanalysis allows you to modify the fiducial points on acquired
waveforms. The details of what modifications can be made depends on
which system option is enabled:
 If the Measurement and 12SL Interpretation option is enabled,
reanalysis allows you to modify Global Measurements.
 If the HEART option is enabled, reanalysis allows you to modify both
Global Measurements and T wave Dispersion.
Reanalyzing an ECG

3. Review the waveforms to determine the accuracy of the system-
selected fiducial points.
For a better view of individual waveforms, use the Leads key to
toggle through the waveforms.
4. After you have analyzed the waveforms, use the following procedure
to adjust the fiducial points:
a. Press the F1 key to toggle through the fiducial points.
The selected point changes size and is highlighted green.
