OpenEP is an open-source library for electrophysiological data analysis, first released in 2020. EP Workbench is the graphical interface for OpenEP which empowers translation by enabling non-technical users to undertake quantitative analysis of electrophysiological data. EP Workbench is cross-platform software, available for Linux, Windows and MacOS operating systems. This paper provides an update on the features and tools added to EP Workbench since initial release. Development is ongoing in the areas of electroanatomic mapping data feature extraction and integration with high performance computing. The addition of an inline code editor ("Work in Progress" workspace) allows implementation of researcher- or project-specific customized algorithms. Close integration with core EP Workbench modules allows Work in Progress algorithms to leverage the functionalities in existing visualization, manipulation and data import/export modules. EP Workbench is supported by an active user and development community. OpenEP and EP Workbench provide the foundations for a forthcoming national UK study (OpenEP|NET) which will create the world's first open-access electrophysiology dataset comprising 2,300 patients with electroanatomic mapping data linked to clinical outcomes. Together, these technical and data availability developments have the potential to kickstart a new era of data-driven diagnosis and therapy for arrhythmia patients.
