Preparation for Monitoring ECG Monitoring ECG, Arrhythmia, ST and QT
7 - 4 TM80 Telemetry Monitor Operator’s Manual
To position the electrodes, follow this procedure:
1. Peel the backing off of the electrode. Visually inspect the contact gel medium for
moistness. If the gel medium is not moist, do not use the electrode patch. Dry elec-
trode patches are not conductive.
2. Attach the electrode patch to the skin at the prepared site. Smooth the electrode
patch down in a circular motion to ensure proper skin contact. If using soft gel
electrodes, never push down directly over the contact gel medium as this may dis-
place the gel and cause monitoring artifact. If using hard gel electrodes, it is rec-
ommended that during application, the center of the electrode should be slightly
pressed onto the skin to ensure direct contact. Consult the electrode manufac-
turer’s instructions for specific use. Ensure all the electrodes are applied to the
patient properly.
3. Secure the lead wires to the patient according to hospital practice.
NOTE
• Avoid placing electrodes directly over bone prominences or over any
high activity movement areas such as shoulders or arms because muscle
motion produces electrical activity. If an electrode is placed over a large
muscle such as the pectorals, the device may detect this additional mus-
cle activity and could lead to false arrhythmia calls.
• Using a Transcutaneous Electrical Nerve Stimulator (TENS): since A tens
UNIT transmits electrical impulses, avoid placing ECG electrode near the
TENS electrodes. ECG electrodes may need to be repositioned and the
ECG lead viewed may need to be adjusted until the optimum ECG trac-
ing is obtained.
NOTE
• To prevent evaporation of the contact gel medium, peel the backing off
of the electrode patch only when it is ready for use.
• If using the snap type lead wires, attach the electrode to the lead wire
before placing the electrode on the patient.
