*4.3. Physionet QT-Database*

This dataset was designed for the evaluation of the ECG heartbeat segmentation algorithms. It has annotations for each record, with boundaries of each heartbeat. This dataset includes not only records of healthy people, but also records of patients with cardiological disorders. Because of this, all annotations were manually reviewed in order to select records with a normal ECG rhythm. The following records were selected: sel103, sel117, sel123, sel16265, sel16272, sel16273, sel16420, sel16483, sel16539, sel16773, sel16786, sel17152, sel17453, sel301, sel302, sel306, sel307, sel310, sele0111, sele0124, sele0133, and sele0210. The Physionet QT database is available in [20,21].
