Large Amplitude Pacer Pulses
WARN IN G: Some pacemakers, especially external
pacemakers, emit pulses with amplitudes far exceeding
those shown in the pacer pulse rejection table. The mon-
itor may misinterpret such pulses as valid QRS com-
plexes and may fail to detect cardiac arrest
.
Transcutaneous Electrical Nerve Stimulators (TENS)
TENS signals are similar to pacemaker spike signals and may be
accidentally labeled as such by the monitor.
WARN IN G: Valid QRS complexes following mislabeled
TENS signals could be rejected. The result may be false
asystole or low heart rate alarms. If TENS signals con-
tinue to be interpreted as pacer spikes, turn the pacer
detection off.
