ST/AR Arrhythmia
2-8 Product Safety
For Paced
Patients
WarningWarning
The output power of the transceiver and other sources of radio frequency
energy, when used in the proximity of a pacemaker, can be sufficient to
interfere with pacemaker performance. Due to the shielding effects of the
body, internal pacemakers are somewhat less vulnerable than external
pacemakers. However, caution should be exercised when monitoring any
paced patient.
In order to minimize the possibility of interference, position electrodes,
electrode wires, and the transceiver as far away from the pacemaker as
possible.
Consult the pacemaker manufacturer for information on the RF
susceptibility of their products and the use of their products with the
IntelliVue Telemetry System. See the IntelliVue Information Center
Instructions for Use for additional information on monitoring paced
patients.
ST/AR Arrhythmia
WarningWarning
During complete heart block or pacemaker failure (to pace or capture), tall
P-waves (greater than 1/5 of the average R-wave height) can be erroneously
counted by the arrhythmia algorithm, resulting in missed detection of
cardiac arrest.
