ANALYSIS SYSTEM AND ANALYSIS METHOD
An analysis system and method are provided for analyzing physical information and acquiring biological data of a user from a biological data acquisition sensor. The exemplary analysis system includes a circadian rhythm calculator that calculates an average circadian rhythm of the user; an autonomic nerve analyzer that performs autonomic nerve analysis based on a variation in the biological data; and a physical information analyzer that weights an autonomic nerve analysis result analyzed by the autonomic nerve analyzer with a weighting coefficient set based on a measurement time at which the biological data of the user is acquired and a cycle of the average circadian rhythm. The physical information analyzer also estimates a change in a circadian rhythm with respect to the average circadian rhythm based on the weighted autonomic nerve analysis result.
Methods and systems for generating integrated substrate maps for cardiac arrhythmias
An electrophysiology map, for example a map of arrhythmic substrate, can be generated by acquiring both geometry information and electrophysiology information pertaining to an anatomical region, and associating the acquired geometry and electrophysiology information as a plurality of electrophysiology data points. A user can select two (or more) electrophysiological characteristics for display, and can further elect to apply various filters to the selected electrophysiological characteristics. The user can also define various relationships (e.g., Boolean ANDS, ORs, and the like) between the selected and/or filtered characteristics. The user-selected filtering criteria can be applied to the electrophysiology data points to output various subsets thereof. These subsets can then be graphically rendered using various combinations of colorscale, monochrome scale, and iconography, for example as a three-dimensional cardiac electrophysiology model.
