Mapping electric bulk conductivity in the human heart

In addition to electro-physiological examinations, mapping the passive bulk conductivity would complete a comprehensive characterization of myocardial tissue. The technique to measure this conductivity with MRI, called “Electrical Properties Tomography” (EPT), has been developed some time ago, but not yet explored for the human heart. This study investigated and confirmed two basal goals of cardiac EPT: (a) that cardiac EPT is technically feasible, (b) that quantitative conductivity values of myocardium and blood, obtained from a small group of volunteers, are in line with expectations from literature.
