1-7
Pacemaker Amplitude
2 mV steps from -20 mV to +20 mV and settings of ±50,
±100, ±200, ±500, and ±700 mV
Accuracy is 10 % of setting ±0.2 mV
Pacemaker Width

Both "amplitude" and "width" have manual and auto-
stepping modes. Auto-step time interval is 6 seconds.
Pacemaker Input
The minimum pulse amplitude is ±0.1 mA or ±1.5 V
The input impedance is 15 ke
Defibrillator Section
The simulator has three training scenarios each with a preprogrammed series of ECG
waveforms that require clinical intervention with a cardiac defibrillator. The operator
interacts with these scenarios by either manually selecting functions on the simulator
keyboard, or inputting an attenuated defibrillator discharge signal through the "SYNC"
input. This stimulus can be generated by discharging a defibrillator into a Fluke
Biomedical defibrillator analyzer. Just connect the analyzer's 1000:1 oscilloscope output
to the simulator's "SYNC" input to automatically sequence the ECG waveforms.
Emergency 1:
ECG starts normally, then after 2 PVCs (R on T) it
changes to ventricular fibrillation. Defibrillation
converts back to normal.
Emergency 2:
ECG starts normally, then changes to ventricular
tachycardia, and then to ventricular fibrillation.
Defibrillation converts back to normal.
Elective Cardioversion:
ECG shows atrial fibrillation. A properly timed
defibrillation pulse converts back to normal. A late
defibrillation pulse causes ventricular fibrillation. The
cardioversion time window is ±100 ms from the R-
wave peak.
"SYNC/A PACE" Input Level: A positive voltage transition through ±0.4 V triggers
this input. Maximum voltage is ±35 V and input
impedance is approximately 15 ke.
