3.1.2 Connecting the Patient Cable to Electrodes
Align all lead wires of the patient cable to avoid twisting, and connect the lead wires to the
reusable electrodes or the alligator clips. Firmly attach them.
The identifiers and color codes of electrode connectors used comply with IEC/EN requirements.
In order to avoid incorrect connection, the identifiers and color codes are specified in Table 3-1.
Moreover the equivalent codes according to American requirements are given in Table 3-1 too.

3.2 Preparing the Patient
3.2.1 Instructing the Patient
Before attaching the electrodes, greet the patient and explain the procedure. Explaining the
procedure decreases the patient’s anxiety. Reassure the patient that the procedure is painless.
Privacy is important for relaxation. When possible, prepare the patient in a quiet room or area
where others can’t see the patient. Make sure that the patient is comfortable. The more relaxed
the patient is, the less the ECG will be affected by noise.
