Background: Wearable devices play an essential role in the early diagnosis of heart diseases. However, effective management of long-term ECG measurements (1-3 weeks) by a telemedicine center (TMC) requires specifically designed software.Method: We used the multiplatform framework .NET to build the application. Deep-learning models for QRS detection, classification, and rhythm analysis were trained in the PyTorch framework; models were trained using data from Medical Data Transfer, s. r. o., Czechia (N=73,450 and 12,111) . The ONNX runtime libraries were used for model inference, including acceleration by graphic cardsResults: The pre-production benchmark (recordings of 82 patients) showed a mean accuracy of 0.97 ± 0.04 for QRS detection and classification into three classes; it also showed a mean accuracy of 0.97 ± 0.03 for rhythm classification into seven classes. Conclusion:The presented software is a fully automated, multiplatform, and scalable back-end application to process incoming ECG data in the TMC. Although it is not freely accessible, we are open to considering processing ECG data for research and strictly non-commercial purposes.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
