Systems And Methods For Noninvasive Spectral-Spatiotemporal Imaging of Cardiac Electrical Activity

摘要

A system and method for non-invasively generating a report of cardiac electrical activities of a subject includes determining, using cardiac electrical activation information, equivalent current densities (ECDs). The ECDs are assembled into time-course ECD information and a spectrum of the time-course ECD information is analyzed to determine peaks for spectral characteristics of atrial fibrillation (AF). The spectral characteristics of AF are correlated with potential electrical sources of the AF and a report is generated indicating the potential electrical sources of the AF spatially registered with the medical imaging data.

主权项

1. A system for non-invasively generating a report of cardiac electrical activities of a subject, the system comprising:
a first input configured to receive anatomical information acquired from a region of interest in the subject including a heart of the subject; a second input configured to receive physiological information acquired from the subject related to the heart of the subject; a processor configured to:
determine, using the physiological information, equivalent current densities (ECDs);determine, using the ECDs, at least one of activation sequences (AS) and dominant frequency (DF) information for the heart of the subject; andgenerate a map of the heart of the subject using the anatomical information and the at least one of AS and DF information illustrating a spatial distribution of electrical information over at least a portion of the heart of the subject.
