Messages or Troubles
The printed ECG waveform is
23
out of the grid area of the
printing paper.
Baseline drift.
Symptom: The printed ECG
24
baseline irregularly moves up
and down.
Solutions
The limb electrode clamps are
attached too tightly?
If the interference cannot be
cleared after the above measures,
use an EMG filter, and the recorded
waveform is slightly attenuated.
It is caused by the great fluctuation
of the waveform.
Set the sensitivity to "Auto". The
device will automatically adjust the
sensitivity according to the
amplitude of the ECG signal.
Check the following aspects of the
device for solving problems:
The electrodes are firmly
attached?
The lead wires are properly
connected to the electrodes?
The electrodes and the
patient's skin are clean?
Whether enough conductive
paste is applied to the
electrodes and the patient's
skin.
During the recording, the
patient moves or breathes.
Mixed use of old and new
electrodes.
If the interference cannot be
cleared after the above measures,
use an ADS filter.
