Detect Pace
Safety Considerations
WARNINGS
FALSE CALLS—False low heart rate indicators or false
asystole calls may result with certain pacemakers because of
electrical overshoots.
MONITORING PACEMAKER PATIENTS—Monitoring of
pacemaker patients can only occur with the pace program
activated.
PACEMAKER SPIKE—An artificial pacemaker spike is
displayed in place of the actual pacemaker spike. All
pacemaker spikes appear uniform. Do not diagnostically
interpret pacemaker spike size and shape.
PATIENT HAZARD— A pacemaker pulse can be counted as a
QRS during asystole in either pace mode. Keep pacemaker
patients under close observation.
RATE METERS—Keep pacemaker patients under close
observation. Rate meters may continue to count the pacemaker
rate during cardiac arrest and some arrhythmias. Therefore, do
not rely entirely on rate meter alarms.
CAUTION
FDA POSTMARKET SAFETY ALERT—The United States
FDA Center for Devices and Radiological Health issued a
safety bulletin October 14, 1998. This bulletin states "that
minute ventilation rate-adaptive implantable pacemakers can
occasionally interact with certain cardiac monitoring and
diagnostic equipment, causing the pacemakers to pace at their
maximum programmed rate."
The FDA further recommends precautions to take into
consideration for patients with these types of pacemakers.
These precautions include disabling the rate responsive mode
and enabling an alternate pace mode. For more information
