We often get asked about problems with ECG interference and it is almost always due to an external factor. Here are some handy tips to rectify "noise" on ECG traces;
• Make sure you are using genuine Welch Allyn/Hillrom resting tab electrodes. They feature a higher grade conductive gel resulting in better performance
• Electrode adaptors can build up residue from the electrodes and should be cleaned with alcohol on a regular basis
• Make sure you have any AC, Muscle and Baseline filters turned on
• Avoid electrical interference from devices such as examination couches and fridges by not sitting the lead wires near them
