1 - Plot Set Selection Feature
The
Plot Set Selection
control allows the user to change the visual selection between:
•
Limbs and Augmented Leads
displays LEAD I, LEAD II, LEAD III, aVR, aVL, and AVF signals,
•
Chest Leads
displays V1 - V6 signals.
NOTE:
For display that shows 6 leads combined, the ECG signals have any DC offset removed and
a different offset added to the signal to display the signals as shown. To see the raw ECG
data, you can select the individual signals as described below in the Zoom feature (box 4).
2 - ECG Separation Feature
The
ECG separation
control toggles the vertical distance between the input plots. This capability is
useful when ECG signals are large and require more separation to avoid overlap, or to collapse the
range between signals when the ECG signals are small.
3 - Post Processing Filters Feature
The
Post Processing Filters Features
controls provides a low-pass, a 50Hz/60Hz notch, and a high-
pass digital filters for post-processing the data from the ADS1298R. To activate each filter, the
Enable
checkbox should be checked. To disable the filter, the
Enable
checkbox should be unchecked. Any
combination of the three digital filters can be used by enabling the respective filter.
