Rezumat:

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.
