Processing of medical data has been long reserved for researches in the field. There were numerous attempts at creating unified tools for reading and processing them, however existing solutions are either cumbersome to use or proprietary with bad documentation. We present a new framework for interaction with ECG domain problems. VisECG framework aims to simplify process of gathering and processing of ECG medical data, and therefore ease the learning curve for new researches in the field. Its design enables a standardized access to multiple file formats and interfaces currently used in the field of ECG research. We developed simple applications using the framework as a core interface to access, process and write data. In the article we present our implementation and evaluate usability and functionality of the framework and produced applications.
