4.1 Lead Placement Procedures
Site preparation and ECG electrode placement directly impact the quality of an ECG signal.
Optimizing an ECG signal is imperative for accurate monitoring.
The processes involved in successful lead placement include:
•Skin Preparation
Electrode Patches
Lead Placement Methods: AHA and IEC
4.1.1 Skin Preparation
Proper skin preparation is essential to obtain accurate ECG data. Electrode sites should be
clean, dry and should provide a smooth flat surface. Incidental electrical activity and
inaccurate readings may occur due to incorrect skin preparation.
The following skin preparation is recommended for secure patch application:
1. Shave the chest hair in a 2-4 inch diameter of the electrode site.
2. Use a dry gauze pad to remove excess skin oils, skin cells and residue from the
electrode sites. Never rub the skin until it is raw or bleeding.
NOTE: Prepare the electrode site with alcohol only if the skin is
extremely greasy. If alcohol is used as a drying agent,
always allow the skin to dry before placing the electrode
patch on the skin.
4.1.2 Electrode Patches
NOTE: Store electrode patches at room temperature and open just
prior to use.
NOTE: Avoid more than one type of electrode on a patient because
of variations in electrical resistance.
NOTE: Avoid placing electrode patches directly over boney
prominences or over any high activity movement areas such
as shoulders or arms because muscle motion produces
electrical activity. If an electrode patch is placed over a large
muscle such as the pectorals, the monitor may detect this
additional muscle activity, which could lead to false
arrhythmia calls.
1. Peel the backing off of the electrode patch only when it is ready for use to prevent
evaporation of the contact gel medium. Visually inspect the contact gel medium for
moistness. If the gel medium is not moist, do not use the electrode patch. Dry electrode
patches are not conductive.
NOTE: If using the snap type electrode wires, attach the electrode
patch to the lead wire before placing patch on the patient.
