ECG tests
Equipment
Use the following equipment for these tests:

A multiparameter patient simulator.

ECG patient cable

ECG leadwire set
5 leadwire ECG test
Perform this test if the patient monitor acquires 5 leadwire ECG data.
Connections
1. Attach the ECG patient cable and ECG leadwire set to the ECG/
RESP connector on the patient monitor and connect the leadwires to
the patient simulator.
Patient Simulator Configuration
2. Set up the patient simulator as follows:

Heart rate – 80 bpm.

Heart rate amplitude – 1.0 mV.

5-leadwire ECG patient cable properly attached.
3. Admit the patient to the monitor.
Normal Sinus Rhythm Procedures
1. Observe the following:

ECG lead II is displayed and is noise-free

Heart rate of 80 ±1 bpm is displayed

With QRS tones enabled, an audible tone sounds with each
Rwave (QRS complex)
2. Verify ECG leads I, II, III, aVL, aVF, and aVR are available to view
and are noise-free.
Pacemaker Detection Procedures
1. Select DETECT PACE and set to PACE 2 .
2. Select a pacemaker pulse on the simulator.
3. Observe the following while you view ECG leads I, II, III, aVL, aVF,
and aVR:

a “P” appears above the PVC count indicating pacemaker pulse
detection is enabled, and

the heart rate still reads 80 ±1 bpm.
