z The patient should keep quiet
z Change the limb electrodes if it is too tight.
z If the EMG interference still exists, please apply EMG filter .The waveform will be
weakened a little and have obvious effect for the weakening of R wave.
7.6 Baseline Drift
Phenomenon: The baseline of the recorded ECG waveforms wandering as shown in the
following ECG waveforms.
Solutions:
z Make sure the electrodes are well connected
z The lead wire and electrodes are well connected
z Check the cleaning of the electrode and patient skin
z Electrode gel is applied on the electrodes and skin
z Keep the patient from motion or hyperventilation
z The old electrodes and new ones are mix use
z If the problem still exists, please apply baseline filter.
