AI Technical Summary

Problems solved by technology

Although BSPMs can indicate local cardiac electrical activity in a different manner than conventional ECG techniques, these BSPM techniques typically provide relatively low-resolution, smooth projections of cardiac electrical activity that are not conducive to visual detection or identification of cardiac event locations (e.g. Arrhythmia origin) and details of regional activity (eg, number and location of arrhythmogenic foci in the heart)
[0016] Because localization of arrhythmias using electrical potentials is inaccurate, successful treatment of arrhythmias is difficult and has demonstrated limited success and reliability

Embodiment Construction

[0124] Various exemplary embodiments will be described more fully hereinafter with reference to the accompanying drawings, in which some exemplary embodiments are shown. However, inventive concepts may be embodied in many different forms and should not be construed as limited to the exemplary embodiments set forth herein.

[0125] It will be understood that, although the terms first, second etc. are used herein to describe various elements, these elements should not be limited by these terms. These terms are used to distinguish an element, but do not imply a necessary order of the elements. For example, a first element could be termed a second element, and, similarly, a second element could be termed a first element, without departing from the scope of the present invention. As used herein, the term "and / or" includes any and all combinations of one or more of the associated listed items. And a "combination" of related listed items need not include all of the listed items, bu...

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.
