Start: This button is used to start and end the system arrhythmia detection. The default is OFF. When the VPC is
not ON, the learn key is disabled. Press this key and the system enters learning mode. The Start changes to End.
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
4.27
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 arrhythmia 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 relearn arrhythmia by pressing “Learn” button
and capture correct template.
☞ Press print key to print the arrhythmia data list. If a piece of record is chosen, press print key to print the
current ECG waveform and arrhythmia waveform on the VPC Screen.
