We computed and compared autocorrelation maps (AC maps) from
ECG recordings obtained on human thorax shaped electrolytic filled
tanks in which a perfused dog heart was immersed at various
geometrical displacements (in a range of 5–6~cm on $x$, $y$ and $z$),
by considering the correlation between instantaneous potential
distributions at each pair of instants over the QT interval. The
correlation coeficient between AC maps was in the range of 0.92–0.99
while between the corresponding QRST integral maps it was in the range
of 0.55–0.87, prooving that AC maps are ECG representations with
low dependence on the thorax electrical properties.
