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.
