Noninvasive Pacing
9.1 Overview
In pacer mode, the patient’s ECG is monitored through ECG lead set and pace pulses are delivered through multifunction
electrode pads. The pads cannot be used to monitoring ECG rhythm and deliver pacing current at the same time.
A white pacing marker is shown on the ECG waveform each time a pacer pulse is delivered to the patient. If pacing in
demand mode, white R-wave marker also appears on the ECG waveform until capture occurs.
During pacing, both ECG and SpO

parameters continue to be monitored and parameter alarms remain active.
In demand mode pacing, a 3-lead or 5-lead ECG cable and electrodes are required to acquire ECG signal. Pace pulses are
delivered through multifunction electrode pads. However, the pads cannot be used to monitor the ECG and deliver pace
pulses simultaneously.
NOTE
z
In Pacer mode, arrhythmia analysis is supported and available arrhythmia alarms are asystole, ventricular
vibrillation and ventricular tachycardia.
9.2 Safety
WARNING
z
Heart rate displays and alarms function during pacing, but they can be unreliable. Observe the patient
closely while pacing. Do not rely on the indicated heart rate or heart rate alarms as a measure of the
patient’s perfusion status.
z
To avoid explosion hazard when pacing a patient who is receiving oxygen delivery, properly route the
oxygen delivery tube. Do not keep it close to the multifunction electrode pads.
