-- 56 -- User Manual for Electrocardiograph
CAUTION
Set EMG filter to lower value if EMG interference still exists after the above checks are completed, and keep in
mind that the recorded ECG waveform, particularly R wave, will be somewhat attenuated.
8.6 Baseline Wander
Irregular movement of ECG baseline due to baseline drift is shown as below:
Causes of baseline wander are varied, please do following checks one by one
：
1. Make sure the electrodes are in good contact with skin.
2. Make sure the connection between the Animal Cable and electrodes is normal.
3. Make sure the electrodes are clean and animal skin contacted with the electrodes has been well pretreated.
4. Make sure the electrodes and skin are covered with ECG gel.
5. Keep the animal silent and motionless, and keep the animal from hyperventilation.
6. Used electrodes shall not be utilized with new ones in using examination.
CAUTION
If the problem still can’t be cleared, please turn up the baseline wander filter, keep in mind that the recorded ECG
waveforms, particularly T wave and ST segment, will be somewhat distorted .
