Generating Test Waveforms
The Analyzer generates a series of test waveforms designed to verify the
accuracy of ECG machine / monitors. These waveforms, shown in Table 2-2 ,
are available for simulation via ECG jacks or paddle plates and are calibrated
for lead II at 1 mV.
Table 2-2. Test Waveforms
ECG Performance Arrhythmia
30 BPM 30 BPM Pulse Atrial Fibrillation
60 BPM 60 BPM Pulse Atrial Flutter
120 BPM 2 Hz Triangle (2 mV) Atrial Tachy
180 BPM 0.125 Hz Square (50 % dc) Idioventricular
240 BPM 2.0 Hz Square (50 % dc) PVC
10 Hz Sine R on T
40 Hz Sine Run
50 Hz Sine Ventricular Fib.
60 Hz Sine Ventricular Tachy
100 Hz Sine
To generate waveforms for testing:
1. Turn the defibrillator to be tested to ON.
2. Connect the ECG patient leads to the Analyzer as shown in Figure 2-7.
