WARNING
ECG cables can be damaged when connected to a patient during defibrillation or using
other high frequency equipment. Check cables for functionality before using them again.
It is recommended to use defibrillator-proof ECG lead to avoid burn.
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 to V6. If you set both to the same value, one of them will
be adjusted to another option automatically. (Figure 13-5)
Figure13-4 ECG Lead
WARNING
In 5-lead mode, Pace detection ±2 mV to ±700 mV; In 3-lead mode, for Pace detection, it
is recommended to set as II, ±2 mV to ±700 mV.
NOTE:
If an ECG waveform is not accurate, while the electrodes are tightly attached, try to
change the leads displayed on the screen.
Normal QRS complex should be:
Tall and narrow with no notches.
With tall R-wave completely above or below the baseline.
With pacemaker spike no higher than R-wave height.
With T-wave less than one-third of the R-wave height.
With P-wave much smaller than the T-wave.
