    摘要: The invention relates to a method of high-resolution mapping of a heart, including: providing a heart mapping apparatus; contacting at least a portion of an intact heart tissue with a voltage-sensitive fluoroscopic dye to generate at least a portion of dyed heart tissue; inserting a first end of the heart mapping apparatus into an intact heart; illuminating the portion of dyed heart tissue with a first range of wavelengths of electromagnetic radiation from the first end of the heart mapping apparatus; collecting a second range of wavelengths of electromagnetic radiation from the portion of dyed heart tissue; and transforming the second range of wavelengths of electromagnetic radiation to at least about 100 points of information, wherein said 100 points of information yields a map of at least one anatomical feature and at least one electrical potential.

    摘要: A method and computer program product comprising an algorithm adapted to execute a method of identifying the spatial coordinates of a sustaining source of fibrillatory activity in a heart by computing a set of point-dependent dominant frequencies and a set of point-dependent regularity indices for a set of products of point-dependent unipolar discrete power spectra and point-dependent bipolar discrete power spectra, derived by spectral analyses of corresponding unipolar and bipolar cardiac depolarization signals simultaneously acquired from a set of points of the heart. A maximum dominant frequency is selected whose associated coordinates identify the point of the sustaining source of fibrillatory activity. The magnitude of the regularity index is interpreted to verify the identification of the spatial coordinates of the sustaining source of fibrillatory activity. When indicated, surgical intervention is directed to the spatial coordinates of the sustaining source of fibrillatory activity.
