On special request to the contributors of the database, recordings may be available at sampling rates up to 10 KHz. Within the header (.hea) file of most of these ECG records is a detailed clinical summary, including age, gender, diagnosis, and where applicable, data on medical history, ...

Electrocardiography (ECG) is a key non-invasive diagnostic tool for cardiovascular diseases which is increasingly supported by algorithms based on machine learning. Major obstacles for the development of automatic ECG interpretation algorithms are both the lack of public datasets and well-defined benchmark...
Due to its simplicity, non-invasive nature, widespread use and diagnostic value, the electrocardiogram (ECG) is one of the primary tools for the first assessment. However, it requires the analysis of a huge amount of time-series ECG-data. Therefore automatic analysis tools have become standard....
The ECG is an important non-invasive diagnostic method for the interpretation and identification of various types of heart disease. Figure 1 shows an illustrative waveform of the ECG signal. Every day, approximately 3 million ECGs are produced worldwide [18]. ECG data contain rich information ...
