8 Monitoring ECG, Arrhythmia, ST and QT
8.1 ECG Introduction
The electrocardiogram (ECG) measures the electrical activity of the heart and displays it on the monitor as
waveforms and numerics. ECG monitoring provides 3-, 5-, 6-, and 12-lead ECG monitoring, ST-segment analysis,
arrhythmia analysis, QT/QTc measurements, and optional 12-lead resting analysis via the Glasgow algorithm.
The associated monitor incorporating ST analysis has the ST label.
The associated monitor incorporating 12-lead has the 12-lead label.
8.2 ECG Safety Information
WARNING
This equipment is not intended for direct cardiac application.
Ensure that the conductive parts of ECG electrodes and associated connectors, including the neutral
electrode, do not come into contact with any other conductive parts including earth.
Always use defibrillation-proof ECG cables during defibrillation.
Do not touch the patient, or metal devices connected to the patient, during defibrillation.
To minimize the hazard of burns during high-frequency surgical procedures, ensure that the
monitor’s cables and transducers never come into contact with the electrosurgery unit (ESU).
To minimize the hazard of burns during use of high-frequency surgical unit (ESU), the ECG
electrodes should not be located between the surgical site and the ESU return electrode.
CAUTION
Only use parts and accessories specified in this manual. Follow the instructions for use and adhere to
all warnings and cautions.
Periodically inspect the electrode application sites to ensure skin integrity. If the skin quality
changes, replace the electrodes or change the application site.
Interference from an ungrounded instrument near the patient or electrosurgery usage can induce
noise and artifact into the waveforms.
8.3 ECG Display
The following figures show the ECG waveform and numeric areas. The display may be configured to look slightly
different.
