Methods: In this study, we present the adaptation of the SSSD-ECG diffusion model to generate high-quality synthetic 12-lead ECGs for Sinus Rhythm\/Normal and Atrial Fibrillation (AF) conditions using 10-second recordings from the 12-lead MIMIC-IV ECG dataset. Results: We validate the utility of the generated ECGs through downstream classification tasks, with models trained on synthetic ECG features achieving an F1-score of 0.80 when tested on real data, and 0.91 when trained on real data and tested on synthetic data. Additionally, blind tests conducted by physicians at two university hospital sites demonstrated that the synthetic signals effectively mimic real ECGs in both morphology and key features. Conclusion: This work establishes diffusion-based models as an effective tool for generating realistic synthetic ECGs, providing valuable resources for model development, supporting testing of clinical decision- making solutions, and enabling research in contexts where real data is scarce or not shareable.<\/jats:p>","DOI":"10.3233\/shti251414","type":"book-chapter","created":{"date-parts":[[2025,9,3]],"date-time":"2025-09-03T10:25:06Z","timestamp":1756895106000},"source":"Crossref","is-referenced-by-count":0,"title":["ECG Synthesis and Utility Analysis - A Diffusion Model Based Approach"],"prefix":"10.3233","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-9468-6311","authenticated-orcid":false,"given":"Sanketa","family":"Hegde","sequence":"first","affiliation":[{"name":"Klaus Tschira Institute for Integrative Computational Cardiology, Heidelberg, Germany"},{"name":"Department of Internal Medicine III, University Hospital Heidelberg, Heidelberg, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Merten","family":"Pr\u00fcser","sequence":"additional","affiliation":[{"name":"Department of Internal Medicine III, University Hospital Heidelberg, Heidelberg, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Nikola","family":"Cenic","sequence":"additional","affiliation":[{"name":"Klinikum rechts der Isar, Technical University of Munich, Munich, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Anatol","family":"Bollinger","sequence":"additional","affiliation":[{"name":"Klinikum rechts der Isar, Technical University of Munich, Munich, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Marie","family":"Arens","sequence":"additional","affiliation":[{"name":"Klinikum rechts der Isar, Technical University of Munich, Munich, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jan","family":"K\u00f6hlen","sequence":"additional","affiliation":[{"name":"Klinikum rechts der Isar, Technical University of Munich, Munich, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Eimo","family":"Martens","sequence":"additional","affiliation":[{"name":"Klinikum rechts der Isar, Technical University of Munich, Munich, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Christoph","family":"Dieterich","sequence":"additional","affiliation":[{"name":"Klaus Tschira Institute for Integrative Computational Cardiology, Heidelberg, Germany"},{"name":"Department of Internal Medicine III, University Hospital Heidelberg, Heidelberg, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"7437","container-title":["Studies in Health Technology and Informatics","German Medical Data Sciences 2025: GMDS Illuminates Health"],"original-title":[],"link":[{"URL":"https:\/\/ebooks.iospress.nl\/pdf\/doi\/10.3233\/SHTI251414","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,9,3]],"date-time":"2025-09-03T10:25:07Z","timestamp":1756895107000},"score":1,"resource":{"primary":{"URL":"https:\/\/ebooks.iospress.nl\/doi\/10.3233\/SHTI251414"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2025,9,3]]},"ISBN":["9781643686158"],"references-count":0,"URL":"https:\/\/doi.org\/10.3233\/shti251414","relation":{},"ISSN":["0926-9630","1879-8365"],"issn-type":[{"type":"print","value":"0926-9630"},{"type":"electronic","value":"1879-8365"}],"subject":[],"published":{"date-parts":[[2025,9,3]]}}}
