Start:
This button is used to start and end the system arrhythmia detection. When the ARR is not ON, the
learn key is disabled. Press this key and the system enters learning mode. The Start changes to
Close. Press it again to end the
learning. When “Learn” key change to yellow from gray, it indicates
the learning has finished. After the arrhythmia detection is begins, the system will automatically
detect the arrhythmia waveforms. If arrhythmia is detected, the arrhythmia waveform will be
displayed in the second ECG channel, shown in Figure 4.25
When the system get reset or the patient has change, the arrhythmia needs to be re-learned.
Learn:
Because the arrhythmia detection is based on the normal ECG waveform at the same speed and
same amplitude, when the patient changes, or the arrhythmia detection is incorrect, the arrhythmia
needs re-learn. To better use the learn function, it is recommended to use a good ECG waveform to
learn during the monitoring.
View:
Press this key, and the selected record in the VPC list, which is to be reviewed, becomes the green.
Rotate the Navigation Knob to choose the record and display the corresponding waveform in the
second ECG channel. Press the knob again to exit.
Exit
: press this key to exit the arrhythmia detection screen and return to the system menu.
During monitoring, if arrhythmia is detected, the system will alarm. The VPC alarm is system default and
does not need setup.
During arrhythmia detection, incorrect detection might occur if the non-ECG waveforms (e.g.; square wave
and triangle wave) appear.
Before start 1mv testing, please turn off the VPC detection.
During arrhythmia detection, the arrhythmia module is very important. The system requires a group of
stable ECG waveforms. If the system detects the arrhythmia incorrectly, please make sure the correct ECG
model is used.
Otherwise please re-learn arrhythmia.
4.9 The Menu Setup Screen of the System
4.9.1 Screen Description
During the Mode Selection screen, move the cursor to the “SETUP” and press the knob. The screen shows
the system setting screen as shown in Figure 4.26.
Figure 4.26 System Settings
To set up the system parameter, rotate the knob and move the cursor to the corresponding button, press
the knob to perform the corresponding system settings.
Press the DEF button will make settings returned to the factory default and will not change the patient
document and the recalled data. Our instructions will cover the functions of each button.
