The Generator will deliver one IRE Pulse 50 ms after the rising edge of the triggering signal,
provided that the triggering interval is greater than 500 ms.
There are three conditions the ECG triggering signal may be in:
ECG synchronized, ECG
noisy
, and
ECG no signal
. The last two conditions will prevent energy delivery from starting
or continuing (if already started). On the Pulse Generation screen, the following will be
shown depending on the status of ECG synchronization.
When first entering the Pulse Generation screen (Figure 6-1), the system requires 3.5
seconds to verify the status of the ECG signal. After the 3.5 seconds and BEFORE
delivering a test pulse, if the ECG signal is
synchronized
, the button for
Deliver test pulse
will be active and the Run section of the screen will display:
Click 'Deliver test pulse' to start.

After the 3.5 seconds and BEFORE delivering a test pulse, if the ECG signal is slow or not
present, the button
Deliver test pulse
will be inactive and the Run section of the screen in
Figure 6-2 will display:
"External ECG trigger not present. Please check the connection."
