As long as the ECG has a good quality, no display in online ECG appears on the overview page. In case of insufficient ECG quality, a transparent red rectangle appears on the right side of the online ECG. Depending on the number of ECG channels, either one or three colored rectangles are displayed.
| 1 channel ECG |  Image Modified
| In this case, one ECG channel has a insufficient on quality |
|---|
| 3 channel ECG |  Image Removed Image Added
| In this case the 1st ECG channel is displayed and channels 2 and 3 are of poor quality.
This can be seen from the slightly bolder representation of the channel designation I. If a single-channel ECG display is activated (and only then), channel occupancy of the current ECG channel is highlighted so that you can see which of the ECG channels are of bad or good quality, even if they are not currently displayed.
In this case, the displayed ECG channel 1 is of good quality, but the other two ECG channels (these are currently blanked out) are of insufficient quality. |
