Sensitivity distribution of a unipolar (nonsymmetric) measurement within the region of the spherical heart model for a 100 mm magnetometer - heart center separation. The figure also illustrates the location and size of the magnetometer. This measurement situation corresponds to the measurement of the x
component of the MHV with the nonsymmetric unipositional lead system in the anterior side of the thorax.
(A) Sensitivity distribution at the region of the heart. The magnetometer distance h
and radial distance r
are not shown to the same scale.
