The rate, amplitude, and width of the QRS wave can be changed.
To change the rate:
1. Push  or  to highlight the Rate value.
2. Push .
3. Push  or  to highlight 30, 60, 90, 120, 200, or 250 bpm in the list.
4. Push  to set the rate and go back to the ECG: QRS Detection screen.
To change the QRS 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 0.50 to 5.00 mV that is set in
0.25 mV intervals.
4. Push  to set the amplitude and go back to the ECG: QRS Detection screen.
To change the width of the QT interval:
1. Push  or  to highlight the Width value.
5. Push .
6. Push  or  to adjust the width. Each push of a key increases or decreases the
width 10 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 a QT width of 8 to 200 ms.
7. When the width is set, push  to enter the value and go back to the ECG: QRS
Detection screen.
How to Set Tall T Wave Rejection Test Values (ProSim 8 only)
An ECG monitor must sense and reject a large T wave when it calculates the heart rate.
Use the Tall T Wave Rejection waveform for this test. This wave includes the QRS wave
per EC-13 with a 100 ms width and QT interval of 350 ms. The T wave has a sinusoidal
shape, 180 ms wide, and can be adjusted in amplitude to 0 to 150 % of the overall
waveform amplitude. The rate is set at 80 bpm. To output a tall T wave signal:
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 Tall T Wave Rejection value in the wave group list.
5. Push  to show the ECG: Tall T Wave Rejection in Figure 13 in the display.
