Paper Abstract

Maximal information about the potential distribution across the human chest wall can be obtained by sampling it in an important number of points, distributed according to a pre-defined geometric pattern on the thorax. The classical representation is a set of maps of equipotential lines, taken at different moments of the cardiac cycle. There are important reasons why only specialised cardiologists use this visualisation technique and why it be-longs to the exclusive domain of experimental research: its noise sensitivity and its poor dynamic information content. To overcome these problems, we use a representation of sequences of computer generated images on a video screen, where potential values are mapped to pseudo-colours or gray levels. The use of the visualisation technique as an aid in the study of diagnostic parameters derived from body surface potential maps will be illustrated.
