<b>pECG-Norm: A Large-Scale Standardized Pediatric Normal Electrocardiogram Dataset</b>

ECG signal characteristics vary markedly across age groups, with pediatric recordings differing substantially from those of adults. Establishing a reliable baseline for defining a “normal” pediatric ECG across developmental stages is essential prior to designing algorithms for abnormality detection.

Existing ECG databases are predominantly composed of adult data and lack comprehensive age stratification, while a few pediatric ECG database are only from hospitalized children, resulting in a scarcity of large-scale, publicly available pediatric datasets that accurately reflect typical cardiac physiology of children. To address this gap, we present a large-scale, standardized pediatric normal ECG dataset comprising recordings from children aged 0-6 years.
