Brugada-HUCA: 12-Lead ECG Recordings for the Study of Brugada Syndrome

We present a novel dataset of 12-lead electrocardiogram (ECG) recordings
developed to support the study and classification of Brugada syndrome, a rare
but potentially fatal cardiac arrhythmia. The data were collected
retrospectively from patients evaluated at the Cardiology Department of the
Hospital Universitario Central de Asturias (HUCA) and reviewed by clinical
experts. Diagnostic labels were assigned according to internationally accepted
criteria.

The dataset comprises 363 subjects in total, including 76 patients diagnosed
with Brugada syndrome and 287 healthy control subjects. Each recording is
accompanied by diagnostic information.

This resource aims to facilitate the development and validation of machine
learning algorithms and computational tools for ECG interpretation, supporting
improved early detection and clinical decision-making. The dataset, fully
anonymized in accordance with ethical and privacy standards, provides a
reproducible foundation for collaborative research into Brugada syndrome and
related cardiac conditions.
