11.3.4 Use the 5-lead ECG device.
Users may based on their requirements arrange leads at each channel. Lead names for each channel are
displayed at left to the corresponding waveforms, and users can directly select them for revision. Users can
select proper leads from I, II, III, AVR, AVL, AVF, and V for the channels, as shown in Fig. 0-5. In case a
user selects the same leads, the monitor will automatically adjust to different lead.

Characteristics of a good signal:

High and narrow, without incisura

High R-wave, fully above or below the baseline

Pacing signal no higher than R-wave

T-wave lower than 1/3 of R-wave

P-wave significantly lower than T-wave
To obtain 1mV of calibrated ECG waveform, users should conduct ECG calibration, in such case the
screen will display‖ Don‘t monitor patients during calibration.
