Chapter 7 ECG Monitoring
7.1 Introducon
The electrocardiogram (ECG) is primarily a tool for evaluang the electrical events within the heart. The ECG signals can
be detected by electrodes at the surface of the skin, this device connects ECG signals and represents them on the monitor
as waveforms and numerical value such as heart rate. The S-T segment measurement and arrhythmia detecon can be
done as well by the ECG signals.
The ECG electrodes connect the paent and the lead wires and/or ECG cable, the lead wires and/or cable connect to
the monitor. The electrode type selecon and the locaons of the electrodes are very important to ensure accurate ECG
measurement.
7.2 Safety Informaon
This paent monitor can only be equipped with ECG cable and/or lead wires provided by the manufacturer; using
those from other suppliers may cause improper performance or poor protecon while using debrillator.
Using the same type of qualied and authorized electrodes which should be within its eecve life on the same
paent. If any side-eect such as allergic or smulus skin is found, the measurement should be stopped at once.
It is prohibited to apply the electrode to the paent with lesion and body putrescence.
To the paent with pacemaker, normally the heart rate meter does not count the pacemaker pulse due to the
funcon of pacemaker pulse inhibion, but for the pacemaker with overshoot pulse, the inhibion funcon may
not be fully eecve. So it is important to observe the ECG waveforms carefully and do NOT rely enrely on the
heart rate display and alarm system when monitoring the pacemaker paent.
The improper connecon with electro-surgical unit may not only cause burns, but also damage the monitor or
arouse deviaons of measurement. You can take some steps to avoid this situaon, such as do NOT use small
ECG electrodes, choosing the posion which is far away from the esmated Hertzian waves route, using larger
electro-surgical return electrodes and connecng them with the paent properly.
In operaon mode, the monitor can be used with electro-surgical unit. The monitor’s operator should ensure
the safety of the paents if in use with electro-surgical unit in accordance with the instrucons of this manual.
Aer the eliminaon of high frequency signal and high frequency electromagnec eld, the monitor can be set
to the previous operaon mode within 10 seconds without losing any stored data.
Do not use the monitor with electro-surgical unit in non-operaon mode, nor with large-scale electrical equipment
such as ultrasonic, radiaon and magnec resonance imaging, which may cause electromagnec interference to
the monitor or harm the monitor’s operator.
Conducve parts of electrodes, lead wires and cable are forbidden to contact any other conducve parts (including
ground).
This paent monitor can resist against the discharge of debrillator and the interference from the electro-surgical
