7.5 Changing ECG Settings
Select "Menu" → "ECG" to enter into ECG related settings.
Note
According to the different function configuration, the ECG parameter setting window may
be different, please refer to the monitor in your hand.
Speed: The ECG waveform sweeping speed, 4 options: 6.25mm/s, 12.5mm/s, 25mm/s and
⚫
50mm/s. The factory default is 25 mm/s.
Filter: ECG filtering mode, 3 options: MONI, DIAG, OPER and ST. The default mode is "MONI".
⚫
➢
DIAG: Extended bandwidth to provide the ECG waveforms with the quality of diagnosis level.
➢
MONI: Normal bandwidth to provide noise-free ECG waveforms for effective monitoring.
➢
OPER: Narrow bandwidth to suppress interference from the electrosurgical unit during operation.
➢
ST:Use this mode in ST monitoring.
Note
For different ECG related setting window, and when the ECG filtering mode is set as
"OPER", then items like "Wires", "Lead," and "Pacer" are in grey and nonadjustable.
The "Wires" is fixed to be "3 lead wires", the "Lead" is fixed to be lead "II", and the
"Pacer" is fixed to be unselectable.
If the amplitude of an ECG waveform is too large, the peak of the waveform might not
be displayed. In this case, you should change the waveform gain properly.
Gain: The ECG gain, 7 options: x1/8, x1/4, x 1/2, x 1, x 2, x 4 and Auto. The "Auto" is for automatic
⚫
gain control. The default is "x1".
➢
Auto: auto gain control;
➢
x1/4: 1/4 of the base gain;
➢
x1/2: 1/2 of the base gain;
➢
x1: the base gain;
➢
x2: twice of the base gain;
➢
x4: 4 times of the base gain;
➢
x1/8: 1/8 of the base gain.
➢
The base gain is 10 mm/mV.
Wires: The default is "5-leadwire", it is necessary to select ECG Lead with a "5-leadwire" setting to
⚫
obtain all ECG signals, including Lead I, II, III, aVR, aVL, aVF, and V. The user can also choose
"3-leadwire" setting. When "3-leadwire" is chosen, only electrodes of R/RA, L/LA, and F/LL are
used for detecting ECG signals, and the user can only select ECG signal of Lead I, or II, or III, the
default Lead selection is Lead "II".
Note
If your monitor is configured with 12-lead ECG function, then you can set "Wires" as
"5-leadwire" or "10-leadwire" to obtain ECG signals. When "10-leadwire" is chosen,
then the waveform of lead I, II, III, aVR, aVL, aVF, V1-V6 will be displayed on the All
ECG Trace view.
