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 mV to 0.25 mV by 0.05 mV
intervals and 0.50 mV 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 ms to 200 ms.
7. When the width is set, push

to enter the value and go back to the ECG:
QRS Detection screen.
Set Tall T Wave Rejection Test Values
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. You can adjust the
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 on 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 11 on the
display.
