BeneVision TM80 Telemetry Monitor Operator’s Manual 7 - 1
7
Monitoring ECG, Arrhythmia, ST and QT
7.1 Introduction
The electrocardiogram (ECG) measures the electrical activity of the heart and displays it on
the telemetry monitor as waveforms and numerics.
ECG monitoring provides 3-lead, 5-lead, and 6-lead ECG monitoring, ST-segment analysis,
arrhythmia analysis, and QT/QTc measurements.
Operations such as configuring the QRS threshold, adjusting the ST point/ISO point/J
point, configuring the ST template/QT template are performed at the CMS. For details
about these operations, refer to
13 Monitoring with the Telemetry Monitor at the CMS .
7.2 ECG Safety Information
WARNING
•
The telemetry monitor is not suitable for direct cardiac application.
•
Use manufacturer specified electrodes and lead wires.
•
Make sure the conductive parts of electrodes and associated connectors for
applied parts, including the neutral electrode, do not contact any other
conductive parts including earth.
•
Periodically inspect the electrode application site to ensure skin quality. If the
skin quality changes, replace the electrodes or change the application site.
•
Do not touch the patient or any device connected to the patient, including the
bed and gurney, during defibrillation. Otherwise serious injury or death could
result.
•
False low heart rate indicators or false Asystole calls may result with certain
pacemakers because of pacemaker artifact such as electrical overshoot of the
pacemaker overlapping the true QRS complexes.
7.3 Preparation for Monitoring ECG
CAUTION
•
Interference from a non-grounded instrument near the patient and electro-
surgery interference can cause problems with the waveform.
