ECG1200G Electrocardiograph - User Manual
① Whether or not the electrode placement is instable?
② Whether or not the electrodes or lead cables are connected reliably?
③ Whether or not the electrodes and patient skin are cleaned and are smeared enough electric
gel?
④ Whether or not it is caused by patient's movement and breath?
⑤ Whether or not the electrodes or leads are in bad connection?
If you can not clear the interference after having taken all the measures above, use filter.
