I’m working with CARTO exports and calculating voltage maps using ‘drawMap’ using OpenEP, but the results I’m obtaining are not entirely consistent with what I would expect.
With the newer versions of OpenEP, are there any specific considerations or best practices when working with voltage maps?
Thank you.
Hi one of the main things that can cause differences here with what you might expect is how the data are being interpolated on the surface of the chamber model. Not all systems do this in the same way; some systems export only electrogram data; and openep re-interpolates data. Furthermore, settings such as which interpolation method to use and how far from mapping points to interpolate can affect things further.
Our approach these days is to use EP Workbench to inspect and edit the maps where needed. That way you can tell for sure that the data is how you would expected it. You can then export the data into various formats (openep, VTK, CSV, etc) for quantification.
