sensitive ‘Diagnostic” mode or a more filtered “Monitoring” mode. Determine the current mode of operation.
If the current mode is set on “Diagnostic” consider adjusting it to “Monitoring”.

Check the ECG pads impedance.

Contact your current supplier of monitoring pads or your local GE Healthcare representative to determine if a
lower impedance version is available. High impedance monitoring pads are less sensitive to the very low
signal strength from the heart beat and appear to be more prone to pronounced interference.
