We analysed paediatric prevalence data obtained under \u201cReal World\u201d conditions, defined as a diagnosis based on clinical symptoms, family history or incidentally written ECGs without screening or registry programmes. Findings were compared to published data. This single centre cross-sectional study was performed over a 10-year period in Eastern Austria. We collected all patients with genetically and\/or clinically diagnosed IADs (LQTS, SQT, BrS, CPVT, ARVC and laminopathies) and determined the prevalence and paths to diagnosis for each IAD. At the most recent reference date (2024\/12\/31), 112 patients were enrolled, corresponding to a paediatric prevalence of 1:7000 of all IADs. Subgroup analysis revealed a prevalence of 1:13,000 for LQTS, 1:22,000 for BrS, 1:43,000 for ARVC and 1:368,000 for CVPT. Most patients with LQTS (62%) were diagnosed after incidental ECG, whereas BrS (79%) and ARVC (64%) were diagnosed mainly by family screening.\n                    <jats:italic>Conclusion<\/jats:italic>\n                    :\u00a0This first study on the prevalence of paediatric IADs obtained under \u201cReal World\u201d conditions at a tertiary care centre, reports significantly lower numbers compared to published data. Our findings on patients\u2019 paths to diagnosis suggest that LQTS patients may benefit from selected age-dependent screening programmes, whereas for BrS and ARVC, family screening and intensive collaboration with adult care providers are crucial for diagnosis.\n                    <jats:table-wrap>\n                      <jats:table>\n                        <jats:tbody>\n                          <jats:tr>\n                            <jats:td align=\"left\">\n                              <jats:bold>What is Known:<\/jats:bold>\n                              \u2022\n                              <jats:italic>Although hereditary primary electrical disorders are rare diseases, they may account for 30% or more of all sudden cardiac deaths in the young, making early detection in the general paediatric population crucial.<\/jats:italic>\n                            <\/jats:td>\n                          <\/jats:tr>\n                          <jats:tr>\n                            <jats:td align=\"left\">\n                              <jats:bold>What is New:<\/jats:bold>\n                              \u2022\n                              <jats:italic>This is the first study on population-based paediatric prevalence of primary electrical disorders using \u201cReal World\u201d data.<\/jats:italic>\n                              \u2022\n                              <jats:italic>The significant lower numbers demand a change in patient acquisition including screening programmes, registries and intensive intergenerational care of families by close cooperation between paediatric and adult cardiologists.<\/jats:italic>\n                            <\/jats:td>\n                          <\/jats:tr>\n                        <\/jats:tbody>\n                      <\/jats:table>\n                    <\/jats:table-wrap>\n                  <\/jats:p>","DOI":"10.1007\/s00431-025-06646-z","type":"journal-article","created":{"date-parts":[[2025,12,3]],"date-time":"2025-12-03T02:31:09Z","timestamp":1764729069000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Epidemiology of paediatric inherited arrhythmogenic diseases under \u201cReal World\u201d conditions: findings from a 10-year longitudinal study in Eastern Austria"],"prefix":"10.1007","volume":"184","author":[{"given":"Sulaima","family":"Albinni","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Julian","family":"Heno","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Marianne","family":"Gwechenberger","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ina","family":"Michel-Behnke","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Matthias","family":"Gass","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Manfred","family":"Marx","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2025,12,3]]},"reference":[{"key":"6646_CR1","doi-asserted-by":"publisher","first-page":"1277","DOI":"10.1016\/j.hrthm.2005.09.008","volume":"2","author":"R Puranik","year":"2005","unstructured":"Puranik R, Chow CK, Duflou JA et al (2005) Sudden death in the young.
