Abstract
BACKGROUND: The size of myocardial infarction (MI) is of significance for the prognosis. Selvester scores might be valuable for this estimation. OBJECTIVE: To compare the differences in Selvester scores for chronic MI provided from standard and EASI-derived 12-lead electrocardiograms (ECGs) and to compare these scores to the MI size measured by delayed-enhancement magnetic resonance imaging (DE-MRI). METHODS: Thirty-seven patients were studied. In connection with their DE-MRI scan follow-up after chest pain, body surface potential mapping was performed. Standard and EASI 12-lead ECGs were constructed from the maps. Two investigators manually performed the measurements required for scoring with the Selvester system using quad-plot format of... (More)

Standard and EASI 12-lead ECGs were constructed from the maps. Two investigators manually performed the measurements required for scoring with the Selvester system using quad-plot format of the ECGs. One of the investigators repeated this once for the standard leads. RESULTS: Neither the association nor the agreement between MRI and EASI leads or between MRI and standard leads was very strong. CONCLUSIONS: The Selvester QRS scoring system needs further improvement. (Less)
