The placement of the ECG leads will depend on the type of surgery that is being performed. For
example, in an open chest surgery the electrodes may be placed laterally on the chest or on the
back. In the operating room, artifacts may affect the ECG waveform due to the use of ES
(Electrosurgery) equipment. To help reduce this you can place the electrodes on the right and left
shoulders, the right and
left sides near the abdomen, and the chest lead on the left side at
mid-chest. Avoid placing the electrodes on the upper arms. Otherwise the ECG waveform will be
too small.
WARNING
1 When using the monitor with the defibrillator or other high-frequency equipment,
please use counteracting defibrillation ECG lead to avoid cautery.
2 When using Electrosurgery (ES) equipment, do not place an electrode near the
grounding plate of the Electrosurgery device: otherwise there will be a great deal of
interference with the ECG signal.
Using 5-lead ECG Set
You can set the leads on ECG CH1 and ECG CH2 according to your needs. The lead label is
displayed on the upper left part of the waveform. You can set them corresponding to any two
from I, II, III, AVR, AVL, AVF and V1~V6. If you set both to the same value, one of them will
be adjusted to another option automatically. (Figure 12-5)

WARNING
In 5-lead mode, Pace detection ±2mV~±700mV;In 3-lead mode, for Pace detection, it is
recommended to set as II, ±2mV~±700mV.
