Abstract

Several magnetocardiographic studies have been performed which investigated changes in cardiac magnetic field distribution for a number of diseases involving structural and functional changes in the myocardium, such as in hypertrophy or myocardial infarction. In such studies, different approaches have been used to examine and quantify the characteristics of the fields maps [1,2]. However, the continuous change of the map features over time during depolarisation has not been investigated. Here we introduce parameters which permit the discrimination of the effects of recent myocardial infarction on changes in conduction after Q onset as reflected in changes of the magnetic field pattern over time. Goal was to acquire more information on the underlying disease by identifying changes in the magnedc field distribution caused by ischemia or structural heart disease.
