  James LopezAug 15, 2025
  If you see irregular AC line interference on your GE Medical Equipment, it's likely due to muscle artifact caused by patient movements such as hiccupping or coughing. To resolve this, ensure the patient is warm and comfortable, using cushions for support. You can also try to comfort or distract the patient. If the issue persists, enable the muscle filter (20 Hz / 40 Hz) on the device.
