Setting the Analyzer for an Interactive ECG/Pacer
Asystole Mode Simulation
From the ECG main menu, press the softkey labeled
Pacer Interactive. Next press the softkey labeled Wave
Form. If not already displayed above the waveform
softkey label, select the Asystole waveform by pressing
the softkey labeled Wave Form. A scroll box opens where
Asystole is selected by pressing G or H. Set this
waveform into the Analyzer by either pressing the Wave
Form softkey again or one of the other softkeys.
The ECG signal's amplitude and threshold are set using
the same method as that used to select the wave form.
These ECG waves respond to the incoming pacer pulse
by simulating the heart's response to it. The threshold is
the amplitude of the pacer pulse in mA that is required for
the ECG to "see" the pulse and respond to it. Setting it to
zero disables threshold checking and allows the ECG to
respond to all pacer pulses.
As soon as the demand wave option appears, the
Analyzer goes through the ECG signal variations for the
Pacer demand test automatically.

Selecting ECG Arrhythmias

The Analyzer is capable of simulating a number of ECG
arrhythmia waveforms. From the ECG main menu, press
22
the softkey labeled More. Three arrhythmia selections are
displayed above the softkeys: Supraventricular,
Premature, and Ventricular. Pressing the softkey labeled
More again, displays the Conduction arrhythmia
waveforms.
The process for selecting and setting the parameters of all
four arrhythmias are identical. From the ECG main menu,
navigate using the softkeys labeled More and Back until
the desired arrhythmia is displayed above one of the
softkeys. Next, press the appropriate softkey to select the
desired arrhythmia pattern. The next display provides
access to the two parameters each arrhythmia pattern
has: Wave Form and Amplitude. Figure 23 shows the
parameter selections for the Ventricular arrhythmia
waveform.

To select a waveform, press the softkey labeled Wave
Form. A scroll box opens above the softkey label and
pressing G or H scrolls through the selections. To set the
