RF index data Carto

1

Hi I’m wondering if you can help with a query about exported RF ablation data from Carto please?

What I would like to do is to try to get into the Visitag data and establish the impedance drop at a given ablation index, for instance when AI = 400, what is the impedance drop? I would also like to identify the AI (and FTI) at the time point that the impedance drop reaches a certain threshold. I know this is stored in the RFindex.grid part of the structure but I’m not clear how the grid of the Visitags is organized and the time frequency of sampling. Are you able to help with this at all?

Hi John

Thanks for your message. This is possible but I’ll have to remind myself of the exact workflow.

I’ll post again once I’ve worked it out.

Best wishes
Steve
