You can change the amplitude of the T Wave. To change the amplitude:
6. Push

or

to highlight the Amplitude value.
7. Push

.
8. 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.
9. Push

to enter the value and go back to the ECG: Tall T Wave Rejection
screen.
Fetal Simulation
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. You can change the contraction period. 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
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 on the display. See Figure 12.
