Sensed Refractory Period (SRP)
The Analyzer next generates a second simulated ECG
signal immediately trailing the first simulated ECG signal
used to determine the PRP. See Figure 17. This coupling
interval is slowly extended until the simulated ECG signal
falls outside the PRP. The signal is then sensed by the
pacemaker, causing the escape interval to reset. The
result is a longer pacing pulse interval.
To perform a refractory period test, press the softkey
labeled More from the Pacer Main menu to reveal the
menu shown in Figure 15. Next press the softkey labeled
Refractory Period. When the test is completed the PRP
and SRP values are displayed. If at any time the test
needs to be stopped, press the softkey labeled Abort.
When the test is completed, Summary appears over one
of the softkeys and will display a summary of the test
which can be uploaded to a PC.

Simulating ECG Signals
The Analyzer simulates a wide range of ECG signals to
test pacemaker operation. The ECG signals are
categorized under menu selections found at the ECG main
menu. To set the Analyzer’s ECG output, press P to
open the ECG menu. The ECG menu is shown in
Figure 18.
