The syndrome is associated with a complex current distribution and repolarization dispersion. The traditional methods for the diagnosis rely on standard electrocardiographic (ECG) assessment of the cardiac dynamics. Recent advancements in magnetocardiography suggest that the magnetic-field based investigation of cardiac electrophysiology could offer novel perspectives for the investigation of current abnormalities in BrS patients which go beyond the conventional ECG capabilities to capture intricate current distributions. In this work, we propose a framework for the magnetic analysis of action potential disturbances in Brugada syndrome. We exploit a 1D reduced-order cable geometry for analyzing the relation between the pathological electrical activity in saddleback and coved type BrS and the corresponding magnetic field. Also, we compute transmural pseudo-magnetocardiograms and demonstrate their capabilities of detecting both types of BrS. Overall, our result highlight the potential of magnetic-field oriented investigation of cardiac disturbances related to BrS.<\/jats:p>","DOI":"10.1007\/s00249-026-01826-7","type":"journal-article","created":{"date-parts":[[2026,3,4]],"date-time":"2026-03-04T11:30:10Z","timestamp":1772623810000},"page":"187-197","update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Magnetic field based investigation of Brugada syndrome"],"prefix":"10.1007","volume":"55","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-0154-0482","authenticated-orcid":false,"given":"Martina","family":"Nicoletti","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Anna","family":"Crispino","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alessandro","family":"Loppini","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alessio","family":"Gizzi","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Letizia","family":"Chiodo","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Christian","family":"Cherubini","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Simonetta","family":"Filippi","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2026,3,4]]},"reference":[{"issue":"5","key":"1826_CR1","doi-asserted-by":"publisher","first-page":"659","DOI":"10.1161\/01.CIR.0000152479.54298.51","volume":"111","author":"C Antzelevitch","year":"2005","unstructured":"Antzelevitch C, Brugada P, Borggrefe M, Brugada J, Brugada R, Corrado D, Gussak I, LeMarec H, Nademanee K, Perez Riera AR et al (2005) Brugada syndrome: report of the second consensus conference: endorsed by the heart rhythm society and the european heart rhythm association.
