Electric instability after myocardial infarction displayed in body surface potential maps.
A longitudinal study during the first year after myocardial infarction (MI) was performed in 12 patients (pts) to evaluate the reversibility of the electric heart field changes occurring during the acute phase by means of body surface potential mapping (BSPM). Using correlation coefficients we showed that the inversion of electric processes in myocardial depolarization and/or repolarization during acute phase of MI displays irreversible damage of the myocardium that means high risk for the pt and that the healing of infarcted heart is not completed within 6 months after MI at least from the electrical point of view.
