Cables - Performing 12-Lead ECGs
Now that the sensors are in place, bring the cables to the patient and run them up the patient’s mid-line.
Separate the limb cables from the chest cables to reduce tangling them up on top of the patient.
The cables must lie flat on the patient, they must be contained within the body and not put any stress on the sensors.
Any slack in the cables may be taken up by making gentle loops in the cables. Cables that hang off the patient are susceptible to EMI (electromagnetic interference) and can be a source of artifact.
Clip the cable clasps to each appropriate sensor. Double-check each attachment before you run the EKG to ensure good connections i.e. the sensors are not peeling up or dimpled and to make
