ABSTRACT:
In a method for localizing an origination site of electrical heart activity, body surface potentials generated by the heart activity are measured at a number of measuring points with a multi-channel measuring system, and values are stored that characterize the body surface potentials at the measuring points. These values are then compared to comparison values stored in a data bank, the comparison values representing comparison surface potentials that arise from modeled comparison heart activities whose position in the heart is known. The position of that comparison heart activity whose comparison values exhibit the most similarity to the characteristic values is emitted as a localization result. The comparison values are determined using a heart model embedded in a thorax model.
