Introduction Monitoring ECG
7 - 2 TM80/TM70 Telemetry Monitor Operator’s Manual
7.1 Introduction
The electrocardiogram (ECG) measures the electrical activity of the heart and displays it
on the monitor as a waveform and a numeric.
ECG monitoring provides 3-, 5-, and 6-lead ECG monitoring, ST-segment analysis,
arrhythmia analysis, and QT/QTc measurements.
Operations such as configuring QRS threshold, adjusting ST point/ISO point/J point, set-
ting ST template/QT template are performed at the CentralStation. For details about
these operations, refer to Chapter 12 Monitoring with the TM80/TM70 at the CMS.
7.2 Safety
WARNING
• This equipment 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 applica-
tion site.
• Use defibrillation-proof ECG leadwires during defibrillation.
• Do not touch the patient or any device connected to the patient, includ-
ing the bed and gurney, during defibrillation. Otherwise serious injury
or death could result.
CAUTION
• Interference from a non-grounded instrument near the patient and elec-
tro-surgery interference can cause problems with the waveform.
