Effect of Cardiac Phases and Conductivity Inhomogeneities of the Thorax Models on ECG Lead Selection and Reconstruction

Abstract

ECG lead selection and reconstruction were investigated in the present study using ECG source-to-measurement transfer matrices computed in inhomogeneous and homogeneous conductor thorax-heart models, which represent end-systolic and end-diastolic cardiac phases. ECG leads were selected from a set of 120 leads for body surface potential mapping. The transfer matrices of the 120-lead system were reconstructed from a transfer matrix of selected leads. Effects of changing the cardiac phase and the conductivities on reconstruction performance are reported here. The number of selected leads well matched to the results of earlier works conducted by other researchers.
