Article Synopsis
- An electrocardiogram (ECG) measures heart electrical activity and is commonly used to detect heart diseases due to its simplicity and non-invasive nature.
- The study reviews current automated ECG-based methods for heartbeat classification, covering signal preprocessing, segmentation techniques, feature description, and learning algorithms, while also highlighting key databases for evaluation.
- It concludes with a discussion on the limitations of existing methods, future challenges, and proposes a workflow for evaluating new research in this area.
