ECG Warnings, Cautions, and Notes
WARNING! PACEMAKER PATIENTS: Rate meters or rate detection software 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 this manual
for disclosure of the pacemaker pulse rejection capability of this instrument.
WARNING! PACEMAKER PATIENTS: If PACE DETECT is not turned on when monitoring pacemaker
patients, the heart rate readouts derived from the ECG patient connections are likely to
display erroneous high or erratic rates. Keep pacemaker patients under close surveillance. For
pacemaker patients, it may be advisable to select the SpO2 parameter as the primary heart
rate source.
WARNING! Connect only three-lead or ve-lead ECG lead wires from the patient to the ECG patient cable.
Do not connect any other signal source to the ECG patient cable.
WARNING! False low heart rate indicators or false Asystole calls may result with certain pacemakers
because of electrical overshoots.
WARNING! Reliable monitoring of pacemaker patients can only occur with PACE DETECT on.
WARNING! The pacemaker pulse marker shape and size is not to be diagnostically interpreted.
WARNING! Keep pacemaker patients under close observation. Rate detection in the software may
continue to count the pacemaker rate during cardiac arrest and/or arrhythmia conditions.
Therefore, do not rely solely on rate detection alarms.
WARNING! This monitor does not identify or interpret arrhythmia events. The indication of heart rate
may be adversely aected by the presence of cardiac arrhythmias.
CAUTION! A three-lead ECG cable must be used if 3-Lead processing is selected. A ve-lead ECG cable
must be used if 5-Lead processing is selected. Using the incorrect cable for the selected mode
might lead to a oating reference or additional noise on the ECG signal.
NOTE! Follow institutional standards when applying ECG electrodes. Silver/Silver Chloride disposable
electrodes are strongly recommended to avoid polarization eects that result in large input oset
potentials. Use of “squeeze bulb” type electrodes is not recommended.
NOTE! Use only standard AAMI three-lead or ve-lead ECG cables.
NOTE! Line isolation monitor transients may resemble actual cardiac waveforms and thus inhibit heart
rate alarms.
