Monitoring a Pacemaker Patient
A Pacemaker patient usually requires a different electrode patch placement configuration
than a non-pacemaker patient.
Do not place an ECG electrode directly over the pacemaker generator. Place the electrode
patches 3 – 5 inches away from the pacemaker generator area. For example, if the
pacemaker generator is located in the right subclavian area, relocate the Right Arm (white)
electrode closer in towards the center of the chest.
WARNING: Pacemaker patients’ rate meters may continue to count the
pacemaker rate during occurrences of cardiac arrest or
some arrhythmias. Do not rely entirely upon rate meter
alarms. Keep pacemaker patients under close surveillance.
See Appendix section of this manual for disclosure of the
pacemaker pulse rejection capability of this instrument.
CAUTION: Thoracic respiration measurement may interfere with some
pacemakers. Refer to the pacemaker's manufacturer
supplied manual.
Using a Transcutaneous Electrical Nerve Stimulator (TENS)
Since a TENS unit transmits electrical impulses, avoid placing ECG electrode patches near
the TENS electrodes. ECG electrode patches may need to be repositioned and the ECG lead
viewed may need to be adjusted until the optimum ECG tracing is obtained.
