O objetivo do nosso estudo é estimar a imagem dos músculos miocárdicos isquêmicos em ratos. Os magnetocardiogramas (MCG) dos ratos foram medidos por um gradiômetro de alta resolução de 12 canais, que consistia em bobinas captadoras de 5 mm de diâmetro com distância de 7.5 mm entre cada bobina. MCGs de sete ratos machos foram medidos em uma sala magneticamente protegida antes e depois da oclusão da artéria coronária. A imagem de origem foi estimada pela estimativa de norma mínima (MNE). As alterações na imagem da fonte atual pré e pós-oclusão da artéria coronária foram esclarecidas. Como resultado, no segmento ST, a distribuição atual aumentou significativamente na área isquêmica. Na onda T, a direção da distribuição da corrente deslocou-se claramente para o tórax esquerdo. Provamos que o aumento da área de distribuição de corrente no segmento ST estava relacionado à área isquêmica dos músculos ventriculares.

Abstract: The purpose of our study is to estimate the imaging of ischemic myocardial muscles in rats. The magnetocardiograms (MCG) of rats were measured by a 12-channel high resolution gradiometer, which consisted of 5 mm diameter pick-up coils with a 7.5 mm distance between each coil. MCGs of seven male rats were measured in a magnetically shielded room pre and post coronary artery occlusion. The source imaging was estimated by minimum norm estimation (MNE). Changes of the current source imaging pre- and post coronary artery occlusion were clarified. As a result, in the ST segment, the current distribution significantly increased at the ischemic area. In the T wave, the direction of the current distribution clearly shifted to the left thorax. We proved that the increased area of the current distribution in the ST segment was related to the ischemic area of the ventricular muscles.
