Cardiac Ripple Map Visualization for Multi-Parameter EP Diagnosis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrophysiological mapping systems provide coarse visualization by conveying only a singular form of electrophysiological parameter, making it difficult to observe and rely upon for accurate diagnosis of arrhythmias.
Innovation Solution
A system that allows simultaneous visualization of multiple electrophysiological parameters by varying graphical representations such as bar height and color to indicate different EP values, enabling users to configure binning through a graphical user interface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If only a singular electrophysiological parameter is visualized, then the device complexity is reduced, but the measurement precision and diagnostic accuracy deteriorate
Solution Approach 1:
The patent combines multiple electrophysiological parameters (amplitude, fractionation count, activity duration) into a single integrated ripple visualization system. Different parameters are represented through complementary visual attributes of the same graphical element (ripple height for amplitude, ripple color for fractionation count, ripple presence for activity duration), allowing simultaneous visualization without proportionally increasing system complexity
Solution Approach 2:
The patent adds visual dimensions to represent multiple parameters. The ripple graphic is enhanced with multiple visual attributes (height, color, presence) that encode different electrophysiological parameters, transforming a single-dimension visualization into a multi-dimensional representation that conveys more information without requiring multiple separate visualization systems
2Measurement precision
If multiple electrophysiological parameters are visualized simultaneously, then the measurement precision and diagnostic accuracy improve, but the device complexity increases
Solution Approach 1:
The patent merges multiple parameter visualizations into a unified ripple display system where a single graphical element conveys multiple pieces of information through different visual attributes, avoiding the complexity of multiple separate visualization systems
Solution Approach 2:
The ripple graphic serves multiple functions simultaneously: it visualizes amplitude through height, fractionation count through color, and activity duration through presence. This multi-functional design allows a single visualization element to handle multiple parameters, reducing overall system complexity while improving diagnostic capability
3Measurement precision
If detailed electrophysiological data is provided, then the measurement precision improves, but the ease of operation deteriorates
Solution Approach 1:
The patent uses color coding to represent fractionation count, providing an intuitive visual cue that simplifies interpretation. Different colors correspond to different levels of fractionation, allowing users to quickly assess tissue characteristics without complex numerical analysis
Solution Approach 2:
The patent transforms numerical electrophysiological data into visual dimensions (ripple height for amplitude, color for fractionation). This dimensional transformation makes abstract numerical data more intuitively interpretable, improving ease of operation while maintaining measurement precision
