Reconstruction of myocardial current sources from measured surface potentials

An algebraic algorithm is proposed for the reconstruction of the density of equivalent current sources on a spherical surface enclosing the myocardium. The characteristics of the measurement system are considered together with the electrode placing scheme. Reconstruction results are given from actua...

Description
Summary:An algebraic algorithm is proposed for the reconstruction of the density of equivalent current sources on a spherical surface enclosing the myocardium. The characteristics of the measurement system are considered together with the electrode placing scheme. Reconstruction results are given from actual recordings of surface potentials as maps of the density distribution for the equivalent sources for various times in the cardiac cycle.
