Cardiac Ripple Mapping GUI for Multi-Parameter Arrhythmia Diagnosis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrophysiological mapping systems provide a coarse visualization of cardiac data by representing only one electrophysiological parameter, making it difficult to accurately diagnose arrhythmias like atrial fibrillation.
Innovation Solution
A system and method that allows simultaneous visualization of multiple electrophysiological parameters, such as bipolar amplitude and fractionation count, through graphical representations like colored bars, enabling more detailed diagnosis by superimposing these parameters on existing maps.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If only one 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 (bipolar amplitude, fractionation count, and other EP parameters) into a single integrated ripple display. Different parameters are superimposed on the same graphical representation, allowing simultaneous visualization without requiring separate display systems for each parameter, thus improving diagnostic accuracy while controlling system complexity.
Solution Approach 2:
The ripple display serves multiple functions by representing different electrophysiological parameters simultaneously. The same graphical element (ripple) conveys information about bipolar amplitude, fractionation count, and can be extended to other EP parameters, making the visualization system multi-functional and reducing the need for multiple specialized display mechanisms.
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:

Different parameters are superimposed on the same graphical representation, allowing simultaneous visualization without requiring separate display systems for each parameter, thus improving diagnostic accuracy while controlling system complexity.

3Measurement precision
If detailed electrophysiological data is provided, then the measurement precision improves, but the ease of operation deteriorates due to information overload
Solution Approach 1:
The patent applies local quality by providing different levels of detail in different parts of the display. The ripple display provides detailed information where needed (through visual characteristics like height, color, and pattern) while maintaining an overall simplified view. The system can emphasize specific parameters or regions based on diagnostic needs, allowing detailed information to be presented in a structured, easily interpretable manner.
Solution Approach 2:
The patent uses color variations to encode different electrophysiological parameters and their values. By mapping parameters like bipolar amplitude and fractionation count to different color schemes, the system conveys detailed information through visual differentiation rather than text or numerical data, improving both precision and interpretability simultaneously.
