Popis: Fluorescence response of canine heart tissue is studied in an attempt to localize the conduction system atrioventricular (AV) node. Data is collected for 364 nm and 308 nm illumination via a 750 micrometers diameter fiber placed against the tissue. This is done for sample locations in the right atrium, AV ring, and right ventricle, and for a rectilinear grid of sample locations in the AV node region. Sample locations are marked via tissue ablation with a 2.1 micrometers Ho:YAG laser and removed for histological analysis. Fluorescence responses are given for 364 nm and 308 nm illumination. No evidence of distinguishable fluorescence by the AV node is seen at either wavelength.© (1992) COPYRIGHT SPIE--The International Society for Optical Engineering.
