Abstract
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.
