Magnifying History Waveforms
To magnify history event waveforms 2.5 times for more detailed examination:
1. Move the brackets on the History Review screen small window to the desired
location.
2. Press the Expand button. The magnified segment appears. The first wave-
form that appears is the ECG waveform, if ECG is present.
3. Select the Wave button to display the other stored waveforms.
Measuring History Waveforms
You can make and save up to five history waveform measurements for later printing
for bedside monitored and ambulatory patients.
Making Measurements
1. Press Measure on the normal or expanded view of the History Review screen
2. Use the brackets in the small window to display the appropriate wave segment
in the large window.
3. Use the “mouse calipers” to make both horizontal and vertical measurements
in the large window as follows: click/touch on the beginning point of the wave
segment you want to measure and then on the end point. Yellow X and Y
axes, and intermediate measurements appear with each click. Vertical mea-
surements are shown in millimeters (mm), and horizontal measurements are
shown in seconds (sec).
Note: When using a touchscreen display, you can touch and grab the calipers to
measure waveforms.
Saving Measurements
Save the measurement by pressing as many of the caliper buttons below as appropri-
ate. Make sure that the Clear button is not depressed before storing measurements.
R-R saves the R-R caliper measurement in seconds. Heart rates are saved only
with R-R.
Q-T saves the Q-T caliper measurement in seconds.
P-R saves the P-R caliper measurement in seconds.
QRS saves the QRS caliper measurement in seconds.
ST saves the measured distance between the two horizontal calipers in millimeters
(mm).
