Ultraview Digital Telemetry
13
ECG monitoring in telemetry is identical to hardwired ECG monitoring. Refer to
the ECG, Arrhythmia, and ST Analysis chapters of this manual for detailed
descriptions of configurations, displays, and controls. A brief overview of ECG
monitoring follows.
Electrodes
For ECG tracing with telemetry, use silver/silver-chloride electrodes or their
equivalent. Always connect all the electrodes required for a particular lead.
Missing electrodes may result in the loss of ECG tracing. Refer to the ECG
chapter for information on placing the electrodes.
WARNING:
• Use only Spacelabs Medical recommended electrodes.
Some electrodes may be subject to large offset potentials
due to polarization. Recovery time after application of
defibrillator pulses may be especially compromised.
Squeeze bulb electrodes, commonly used for diagnostic
ECG recording, may be particularly vulnerable to this
effect.

N:
• Visually inspect each lead wire for obvious damage and
replace them as needed.
• Only use patient cables and lead wires specified by
Spacelabs Medical. Other cables and lead wires may
degrade performance and may damage the monitor during
defibrillation. Non-Spacelabs Medical cables and lead
wires may also change the required input impedance and
DC offset voltage, affecting monitor performance.
• Do not use stainless steel electrodes.
• Do not allow conductive parts of electrodes and
connectors, including the reference electrode, to contact
other conductive parts, including the ground.
• Poor cable dressing or improper electrode preparation
may cause line isolation monitor transients to resemble
actual cardiac waveforms and inhibit heart rate alarms.
Refer to the ECG chapter in this manual for details on
proper electrode preparation and application.
