ECG Data Management System for Uninterrupted Catheter Ablation Mapping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for exporting and processing electrocardiogram (ECG) data during catheter ablation procedures are cumbersome and time-consuming, requiring the current mapping procedure to be stopped or completed before data can be exported, which hinders efficient data management and processing.
Innovation Solution
A system and method that allows for the concurrent storage of ECG data in two memory portions, enabling the export of ECG data without stopping the mapping procedure, and facilitates the import of processed new data to generate new maps, using user-defined algorithms, while continuing the mapping process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If the mapping procedure is stopped to export ECG data, then data export can be completed, but the mapping procedure efficiency deteriorates
Solution Approach 1:
The patent divides the data storage system into two separate memory portions: a first memory portion that continuously stores ECG data during the mapping procedure, and a second memory portion that stores synchronized data for export. This segmentation allows data export operations to be performed on the second memory portion without interrupting the continuous data acquisition and mapping procedure in the first memory portion, thereby resolving the contradiction between data export completion and mapping procedure efficiency.
2Ease of operation
If the mapping procedure is stopped to export ECG data, then data can be exported, but the procedure duration increases
Solution Approach 1:
The patent implements preliminary action by continuously pre-storing ECG data in the first memory portion during the mapping procedure and maintaining a synchronized copy in the second memory portion. When data export is requested, the system can immediately export from the pre-prepared second memory portion without stopping the mapping procedure or waiting for data accumulation, thus making the export operation easy to perform while minimizing procedure duration.
3Device complexity
If ECG data is stored in one memory portion only, then storage is simple, but data export requires stopping the mapping procedure
Solution Approach 1:
The patent introduces an intermediary mechanism by implementing two memory portions with a synchronization relationship. The first memory portion serves as the primary data acquisition storage, while the second memory portion acts as an intermediary buffer that is periodically synchronized with the first. This intermediary structure enables data export operations to be performed on the second memory portion without affecting the continuous mapping procedure in the first memory portion, thereby improving data management efficiency while maintaining relatively simple storage architecture.
Data Source
AI summary
An ECG data management system is disclosed which includes a first memory portion configured to store ECG data having values corresponding to electrical signals of a heart acquired over time via a plurality of electrodes disposed at different areas of the heart. The system also includes a second memory portion configured to store the ECG data and a processing device configured to manage mapping of the ECG data by performing a mapping procedure including generating map data and one or more maps from the ECG data for display; concurrently storing the ECG data in the first memory portion and the second memory portion; and in response to a request to export the ECG data, stopping the storing of the ECG data in the second memory portion and synchronizing the ECG data stored in the second memory portion with the map data while continuing to perform the mapping procedure.
