Current density imaging on the epicardial surface of the heart

Abstract: IntroductionMagnetocardiographic (MCG) mapping has providedpromising results in locating various intracardiacsources, such as the sites of origin of life-threateningarrhythmias (e.g., [1]). Magnetocardiographic inversestudies with point-like source models, however, aregenerally applicable only for sources confined in asmall volume of tissue, e.g., at the onset of the ventriculardepolarization. After the onset, the electricalactivation spreads in the myocardium as a wavefront,and the...
