Number of electrocardiogram leads displaying the diagnostic coved-type pattern in Brugada syndrome: a diagnostic consensus criterion to be revised

摘要

Aims According to the diagnostic consensus criteria, the electrocardiographic (ECG) diagnosis of Brugada syndrome requires coved-type ≥2 mm ST-segment elevation in >1 right precordial lead (RPL) V1–V3 in the presence or absence of a sodium-channel blocker. However, this consensus has not been evaluated. We aimed to assess the distribution of coved-type ST-segment elevation on RPLs in a large patient cohort to reevaluate the appropriateness of the diagnostic consensus criteria.
