4. Apply the electrodes to the patient.
5. Support the ECG cable so it does not stress the electrode wires, ECG cable connectors,
or electrodes.
Some electrodes may be subject to large offset potentials due to polarization.
This effect is most likely when dissimilar metals are used for different
electrodes, and may be severe enough to prevent obtaining an ECG trace.
Furthermore, recovery time after application of defibrillator pulses may be
compromised when using electrodes of dissimilar metals. Squeeze bulb
electrodes, even if all of the same metal, are particularly vulnerable to this
effect. Stainless steel needle electrodes are prone to having large erratic offset
drifts, and are not recommended.
