Monitoring the Patient’s ECG
Set the Controls
Set the Mode Selector to MONITOR, then press the LEAD button until the desired lead
configuration is selected. The selected lead is indicated at upper right of the display.
If the unit displays the ECG LEAD OFF, POOR LEAD CONTACT, or CHECK PADS message,
inspect the ECG electrodes or therapy electrodes, lead wires, and cables for proper connections.
If heart rate alarms are enabled with paddles selected, the unit displays the messages SELECT
LIMB LEADS and VF ALARMS OFF. If you see these messages, select limb or precordial leads.
If you want to change the size of the displayed ECG waveform, press the SIZE button until the
desired waveform size is displayed. Options are 0.5, 1, 1.5, 2, and 3 times the normal
size (1 cm/mv).
If you want to shut off the heart rate beeper, press the Options, then the QRS VOL OFF
softkeys. To turn it back on, press the QRS VOL ON softkey.
WARNING! Implanted pacemakers may cause the heart rate meter to count pacemaker pulses
during incidents of cardiac arrest or other arrhythmias. Pacemaker patients should be
carefully observed. Check the patient's pulse; do not rely solely on heart rate meters.
Dedicated pacemaker detection circuitry may not detect all implanted pacemaker
spikes; patient history and physical exam are important in determining the presence of
an implanted pacemaker.
Implanted Pacemakers
The R Series device can be configured to detect pacemaker signals from a patient with an
implanted pacemaker and indicate their presence on the display. When pacer pulses are
detected, the device displays a 5mm, vertical, solid line on the ECG trace.
