4.8. Set chart speed and sensitivity
Welch Allyn CardioPerfect offers a wide range of speed and sensitivity. You can adjust the scale
of the ECG by adjusting the chart speed and the sensitivity.
To set the chart speed:
In the View menu, point to Chart speed and select a value. The higher the chart speed,
the more lead signal will be visible.
To set the sensitivity:
In the View menu, point to Sensitivity and select a value. The lower the value, the lower
the peaks in the lead signal will be.
4.9. View one single complex or loop
In the Averages view and the Vector view, you can view one single complex or loop.
To view a single complex or loop:
1. In the Action menu, click Enlarge. The first lead in an ECG (or the first loop in an VCG)
is enlarged. With the autosize function, available from the right-click menu the selected
loop will be shown as large as possible in the available space.
2. To enlarge another lead or loop, select it from the drop down in the upper left corner of
the workspace.
3. To switch off the enlarge function, click Enlarge from the Action menu once more.
4.10. Turn pacemaker on and off
ECG traces can contain artificial pacemaker signal indicators. You can remove this artificial pacer
indicator by disabling the "Show Pacer" selection. To learn how, see Customizing the Resting
ECG software on page 39.
4.11. Apply muscle noise filter
Muscle noise in an ECG signal hides low amplitude signals that may be important for the
interpretation of an ECG. You can remove this noise with a muscle noise filter.
