Figure 13. Tall T Wave Rejection Screen
The amplitude of the T Wave can be changed. To change the amplitude:
1. Push  or  to highlight the Amplitude value.
2. Push .
3. Push  or  to increase or decrease the T Wave amplitude. The amplitude is set as
a percentage of the voltage on the reference lead. The range is 0 to 150 % in 10 %
steps.
4. Push  to enter the value and go back to the ECG: Tall T Wave Rejection
screen.
Fetal Simulation (ProSim 8 only)
The Product simulates a mixed fetal and maternal electrocardiogram (ECG) that occurs
during labor, as well as a selection of pressure waveforms made by uterine contractions.
The contraction period can be changed. There is also a manual contraction.
Note
The maternal heart rate is always a normal sinus rhythm at
80 beats/minute.
The Product does not provide simulations for all types of fetal heart rate tracings and
contraction patterns. A few examples of simulations not provided are:
• Variable decelerations
• Sinusoidal pattern
• Reactive tracing
• Variations in FHR variability
• Tachysystole
How to Set Fetal Heart Values
The Product simulates the fetal/maternal ECG on its regular ECG leads. The maternal
signal is a P-QRS-T wave at half the set ECG amplitude. The fetal signal is a narrow R
wave at full amplitude. Fetal and maternal signals are summed to make a composite
signal.
To do a fetal simulation:
1. Push .
2. Push , , , or  to highlight Fetal Simulation and then push  to show the
Fetal ECG screen in the display. See Figure 14.
