ECG Monitoring: Arrhythmia Troubleshooting
Arrhythmia Troubleshooting
Problem: Inaccurate heart rate
and/or false asystole
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. Click on the patient’s ECG tab.
2. Click on all ECG leads in the Display section 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.
3. If amplitudes are low, electrodes may need to be repositioned or
replaced.
Relearn arrhythmia:
1. Click on the patient’s ECG tab.
2. Click on the Relearn button.
IF PROBLEM CONTINUES: Change to single lead ECG detection and
processing:
1. Click on the patient’s ECG tab.
2. Click on Single Lead in the Lead Analysis section.
3. Click on the ECG leads in the Display section and change top ECG
waveform to display the lead with the greatest amplitude. (At least
0.5 mV amplitude is required for QRS detection.)
