2025-11-14 We’ve added two WPW accessory pathway location algorithms to EP Mobile, the EASY-WPW and the SMART-WPW algorithms. This was made possible by a new app that is in the works, EP Designer. This new app (for macOS) makes it easy to create decision tree algorithms and save them to JSON files that then can be used in EP Mobile without additional coding. In the long run this will make adding new algorithms easier, and it will also allow us to modernize the old algorithm code in the app. Right now EP Designer is just for internal use, but eventually it might have some interest to algorithm and risk score developers, as a means to write and test new algorithms and risk scores.

Old news (is good news)

Over the years I have written on various subjects, not all of them medical. In fact the topics are pretty far-ranging. Take a look.
