At this point, defibrillation can be accomplished either by a defibrillator signal
input or by using the CARDIOVERSION MENU.
3. When defibrillating by a defibrillator pulse signal input through the "SYNC/A
PACE" jack, the timing relationship to the ECG R-wave peak is checked.
If the pulse comes within ±100 ms, defibrillation is successful and the ECG
converts to normal sinus rhythm. The display then shows the following:
cardioversion: sync okay
<F1> <F2> <F3> <F4>
eic134.eps
and, after 3 seconds, changes to:
cardioversion: converted
start hold
<F1> <F2> <F3> <F4>
eic135.eps
This is the end of the sequence. It can be restarted by pressing <Fl>-START.
4. If the pulse signal is outside ±100 ms, defibrillation is late and the ECG changes
to ventricular fibrillation. The display shows:
cardioversion: late
hold
<F1> <F2> <F3> <F4>
eic136.eps
then changes to:
cardioversion: vfib
hold defib start
<F1> <F2> <F3> <F4>
eic137.eps
5. Press <F3>-DEFIB or input a pulse signal through the rear panel "SYNC/A
PACE" jack to defibrillate the simulator and convert the ECG to normal sinus
rhythm.
