Trouble shooting
Problem :
Inaccurate heart rate and/or false a systole.
Solution :
Check ECG signal from Animal:
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 0.5mV amplitude at normal (1X) size. (at least
0.5mV 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.
Problem :
False ventricular calls.
Solution :
Check ECG signal from Animal: (the chest lead may exhibit polarity changes which may
occasionally cause an inaccurate call.)
1. Check/adjust lead placement.
2. Check/perform skin preparation.
3. Check/replace electrodes. (if chest lead is a problem, move the chest lead to another chest
position or leg position.)
Problem :
Inaccurate pacemaker detection
Solution :
Use pacemaker processing:
1. Select ECG parameter label.
2. Display the lead of ECG with the greatest amplitude in the top waveform position.
3. Select ANALYSIS SETTINGS.
4. SELECT DETECT PACE.
