6.3 ECG Operation
ECG Alarm
The alarm will be given when the ECG is out of the upper limit or lower limit.
Warning
•
The upper and lower limits of alarm should be set according to the clinical
conditions of the animal.
Lead Type
5 lead or 3 lead can be selected
Waveform Selection
Choose which ECG waveform data to calculate heart rate.
Waveform Speed
The scanning speed of ECG waveform can be selected as 12.5, 25.0 and 50.0 mm/s.
ECG 1, ECG 2, ECG 3
Selective leads are Ⅰ,Ⅱ,Ⅲ,AVR,AVL,AVF,V.
Gain Setting
When the input signal is large, the peak may be shortened. At this time, the user can
refer to the actual waveform to manually change the ECG waveform gain file to avoid
incomplete waveform display.
The gain of each calculation channel can be selected. There are four levels of gain:
x0.25, x0.5, X1 and x2. The scale of 1mV is given on the left side of each ECG
waveform. The height of a 1 MV scale is proportional to the amplitude of the wave.
Filter Settings
1.
Diagnosis mode, Monitor mode, Surgery mode, Strong mode.
2.
Only in the diagnosis mode can the system provide the real signal without
processing.
In the 'monitoring' and 'operation' filtering mode, ECG waveform will have
3.
varying degrees of distortion. The system can only provide the basic condition of
ECG, which will have a great impact on the results of ST segment analysis.
4.
In the operation mode, the analysis results of AVR may also have some
influence. Therefore, it is suggested that when the interference is small, the
diagnosis mode should be used for animal monitoring as far as possible. More
clean or accurate waveforms can be obtained by filtering.
5.
In the diagnosis mode, the ECG wave without filtering is displayed; in the
monitoring mode, the false alarm may be filtered; in the operating room, the
operation mode can reduce the false error and interference from the
electrosurgical equipment.
