Abstract Provided are a localization system and method useful in the acquisition and analysis of cardiac information. The localization system and method can be used with systems that perform cardiac mapping, diagnosis and treatment of cardiac abnormalities, as examples, and in the retrieval, processing, and interpretation of such types of information. The localization system and method use high impedance inputs, improved isolation, and relatively high drive currents for pairs of electrodes used to establish a multi-axis coordinate system. The axes can be rotated and scaled to improve localization. L'invention concerne un système et un procédé de localisation utiles dans l'acquisition et l'analyse d'informations cardiaques. Le système et le procédé de localisation peuvent être utilisés avec des systèmes qui effectuent un mappage cardiaque, un diagnostic et un traitement d'anomalies cardiaques, à titre d'exemples, et dans la récupération, le traitement et l'interprétation de ces types d'informations. Le système et le procédé de localisation utilisent des entrées à haute impédance, une meilleure isolation et des courants de commande relativement élevés pour des paires d'électrodes utilisées pour établir un système de coordonnées multiaxial. Les axes peuvent être tournés et mis à l'échelle pour améliorer la localisation.
