4. Push  to set the rate and go back to the ECG: R Wave Detection screen.
To change the R wave amplitude:
1. Push  or  to highlight the Amplitude value.
2. Push .
3. Push  or  to adjust the amplitude. Each push of a key increases or decreases the
amplitude in the direction of the key pushed. The Product simulates a heart signal
amplitude of 0.05 to 0.25 mV by 0.05 mV intervals and 0.05 to 5.00 mV that is set in
0.25 mV intervals.
4. When the amplitude is set, push  to enter the value and go back to the R Wave
Detection screen.
To change the width of the R Wave:
1. Push  or  to highlight the Width value.
2. Push .
3. Push  or  to adjust the width. Each push of a key increases or decreases the
width 20 ms for each key push when the value is 20 ms or above and 2 ms when the
value is 20 ms or less. The Product simulates an R Wave width of 8 to 200 ms.
4. When the amplitude is set, push  to enter the value and go back to the R Wave
Detection screen.
How to Set QRS Detection Test Values (ProSim 8 only)
The QRS Detection wave group supplies a signal that you can adjust the width of the QT
interval. This QRS Detection wave includes the R and S waves with relative amplitudes
as specified in EC-13. The R wave is 0.875 of the waveform amplitude and the S wave is
negative at 0.125 of the waveform amplitude. The R wave up slope is 0.4375 of the
waveform width. The R wave down slope is 0.5 of the waveform width. The S wave up
slope is 0.0625 of the waveform width.
To generate a signal for an QRS detection test:
1. Push  to show the ECG screen in the display.
2. Push  or  to highlight the Wave Group value.
3. Push .
4. Push  or  to highlight the QRS Detection value in the wave group list.
5. Push  to show the ECG: QRS Detection screen in Figure 12 in the display.
