Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electro-anatomical mapping techniques struggle to accurately identify vortices indicative of re-entrant arrhythmias due to the congestion of data points and wave vectors, leading to inconsistent qualitative assessments among physicians.
Innovation Solution
A system and method that utilize a processor to define closed loops on an electro-anatomical map, calculate vector sums across these loops, and apply a threshold to quantitatively determine the presence of vortices, enhancing the identification of re-entrant arrhythmias.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If qualitative assessment methods are used for vortex identification, then physician interpretation flexibility is maintained, but identification accuracy and consistency deteriorate due to data congestion
Solution Approach 1:
The patent segments the electro-anatomical map into discrete measurement points with associated vectors, allowing systematic processing of each point's electrical activity data to determine vortex presence independently, thereby improving identification accuracy while managing data complexity through structured division
Solution Approach 2:
The patent transforms qualitative physician assessment into quantitative parameter-based analysis by calculating vector sums and comparing them against predefined thresholds, converting subjective interpretation into objective measurable criteria that improve consistency and accuracy
2Reliability
If quantitative vector sum method is applied, then identification consistency is improved, but computational complexity increases
Solution Approach 1:
The patent establishes quantitative parameters including vector sum calculations and threshold values that transform subjective assessment into objective consistent measurements, ensuring reliable and reproducible vortex identification across different cases and physicians
Solution Approach 2:
The patent replaces the mechanical/manual qualitative assessment process with automated computational algorithms that calculate vector sums and compare thresholds, substituting human interpretation variability with consistent mathematical operations
3Productivity
If manual vortex identification is used, then system simplicity is maintained, but productivity and accuracy deteriorate due to data congestion
Solution Approach 1:
The patent replaces manual visual inspection with automated computational processing that calculates vector sums for each measurement point and compares them against thresholds, dramatically improving identification efficiency while maintaining high accuracy through systematic quantitative analysis
Solution Approach 2:
The system enables self-service vortex identification by automatically processing electro-anatomical map data, calculating vectors, determining vortex presence, and generating results without requiring manual physician interpretation of congested data visualizations

AI summary
A system for identifying vortices in a vector map including multiple vectors, the system includes a processor and an output device. The processor is configured to: (i) define one or more closed loops on the vector map, and (ii) for each closed loop, identify a plurality of the vectors that cross the closed loop, calculate a vector sum of the identified vectors, and decide based on the vector sum whether a vortex is located inside the closed loop. The output device is configured to indicate one or more identified vortices to a user.
