These electrophysiological catheters are navigated and localized with the use of fluoroscopy. More commonly, cardiac mapping is performed with catheters that are introduced percutaneously into the heart chambers and sequentially record the endocardial electrograms with the purpose of correlating local electrogram to cardiac anatomy. The recording and analysis of extracellular electrograms, reported as early as 1915, forms the basis for cardiac mapping. This entire zip file could be read by EAMapReader.Cardiac mapping is a broad term that covers several modes of mapping such as body surface, endocardial, and epicardial mapping. zip file, accompanied by (among others) a file named sh. The file you shared in post #3 is actually the _car.txt file (and I am pretty sure it was named 1-OG_car.txt when it was first exported). ![]() Thus, one could re-create interpolated electric (bipolar, unipolar voltage and LAT) data for each model vertex and add this as a scalar overlay, but this needs to be done in the plugin, since the interpolation is no longer available in the export (I think this is due to the so-called HD coloring feature which became available first in v6 and broke the export when active. For more detail see here: Change in exported data in Carto3 v7 However, electric data per point (NOT per anatomy vertex, but per catheter-acquired point in space) is available in the *_car.txt files. The interpolated electric data which previously was part of the. zip file which you just took out of the export container is ready for import using EAMapReader Extract this file out of the container, using the password you chose. ![]() Inside this password-protected “container” zip file there should be the actual study zip (named “Export_Study_.zip”). zip file with any zip extractor using the password you chose in step 8. zip file which needs to be unpacked first. zip file is exported inside another (encrypted). You have to chose a password for the export. Select this file for export (by clicking the arrow to the right of the file list), select the export target at the bottom of the screen, and hit export. After the prior export (step 3), there should be a file called “Export_Study_.zip” with today’s date and “RawData” in the “Type” column In the “System tools” menu, select the Export Data… button Select Study → Export Study Data… from the menuīack in the start-up screen, select “System” On the start-up screen, select “Review Study”. You might want to point your clinicians to the following step-by-step export tutorial: ![]() Anyone wanting to adopt the project is very : Carto v7 exports should still be importable as anatomy only (without voltage and activation time data). I’ve tried to figure out how to package the extension so that it can be submitted to the extension index, but I never really understood is (it seems you need a full-blown IDE with CMAKE and other version control stuff to package it, not to mention all the unit testing). The fact that the extension was my first encounter with Python might also explain the huge room for improvement in efficiency and coding style. Sorry for not responding : In general, I am still around, but since I am not longer on the research fellowship I was on 2 years ago (when I wrote the extension an learned Python in the process) I do not really have the time for maintenance and improvements.
