Troubleshooting

Problem:
Inaccurate heart rate
and/or false asystole
Revision C
Solution:
Check ECG signal from patient:
1. Check/adjust lead placement.
2. Check/perform skin preparation.
3. Check/replace electrodes.
Check amplitude of ECG waveform:
1. Select ECG parameter label.
2. Select DISPLAY LEAD.
3. Scroll through all ECG leads and check for 0.5 mV amplitude at
normal (1X) size. (At least 0.5 mV amplitude is required for QRS
detection.) For borderline signals, validate on a graph.
4. If amplitudes are low, electrodes may need to be repositioned or
replaced.
Relearn arrhythmia:
1. Select ECG parameter label.
2. Select RELEARN.
IF PROBLEM CONTINUES AND ECG AMPLITUDE IS LOW:
1. Select ECG parameter label.
2. Select ECG SIZE.
3. Select 2X or higher.
4. Close the popup menu.
5. Select RELEARN.
IF PROBLEM CONTINUES: Change to single lead ECG detection and
processing:
1. Select ECG parameter label.
2. Select ANALYSIS SETTINGS.
3. Select LEAD ANALYSIS.
4. Select SINGLE LEAD.
5. Go to PREV MENU.
6. Select DISPLAY LEAD.
7. Assess all the ECG leads and change top ECG waveform to display
lead with greatest amplitude. (At least 0.5 mV amplitude is
required for QRS detection.)
