Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current cardiac mapping techniques struggle to effectively identify and display slow pathways in the heart, which are often responsible for reentrant arrhythmias, making it difficult to target treatment strategies accurately.
Innovation Solution
A system and method that utilize a mapping probe to sense cardiac electrical signals, process them to determine signal features and conduction characteristics, and generate a cardiac map with annotations that highlight slow pathways, allowing for focused treatment of arrhythmias by identifying areas with abnormal conduction velocities or gradients.

Engineering Contradiction Analysis
1Measurement precision
If traditional cardiac mapping techniques are used to map electrical activity in the heart, then comprehensive electrical data can be collected, but slow pathways responsible for reentrant arrhythmias cannot be effectively identified or displayed
Solution Approach 1:
The patent changes the parameter of conduction velocity by calculating it from activation times and displaying it on the cardiac map. This allows slow pathways to be identified through velocity thresholds, transforming invisible electrical patterns into visible anatomical features on the map.
Solution Approach 2:
The patent adds a new dimension of conduction velocity information to the traditional cardiac map display. By overlaying velocity data and annotations on the anatomical map, slow pathways become visually distinguishable through color coding and graphical markers, enhancing the informational density of the display.
2Quantity of substance
If comprehensive electrical signals are measured at multiple positions, then detailed cardiac electrical activity data is obtained, but the data processing complexity increases
Solution Approach 1:
The patent extracts only the essential feature of conduction velocity from the comprehensive electrical signal data. By calculating velocity from activation times and displaying selective annotations, the system filters out redundant information while preserving the critical slow pathway data needed for arrhythmia identification.
Solution Approach 2:
The patent applies partial action by selectively displaying only certain signal features that meet velocity criteria rather than processing and displaying all possible electrical signal characteristics. This reduces processing complexity while maintaining diagnostic effectiveness for identifying slow pathways.
