Configurable ECG Comparator Display for Arrhythmia Review
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing healthcare devices, such as wearable cardioverter defibrillators, struggle to efficiently capture and compare electrocardiogram (ECG) data for effective analysis and monitoring of heart conditions, particularly during arrhythmia events, leading to overwhelming data volumes that hinder timely medical intervention.
Innovation Solution
A configurable comparator module (CCM) within a wearable medical device (WMD) captures and displays portions of ECG data based on predetermined parameters, enabling concurrent comparison of normal and arrhythmia ECG data on a remote interface for healthcare professionals, facilitating improved analysis and monitoring.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the wearable medical device captures and stores comprehensive ECG data for monitoring, then the quantity of stored information increases, but the device complexity and data management burden increase
Solution Approach 1:
The patent extracts and stores only specific portions of ECG data that are relevant for comparison during arrhythmia events, rather than storing all ECG data. The configurable comparator module identifies and captures only the necessary ECG segments (first portion before arrhythmia, second portion during arrhythmia) for analysis, reducing the overall data volume while maintaining clinical usefulness.
Solution Approach 2:
The patent segments ECG data into distinct portions: a first portion captured before an arrhythmia event and a second portion captured during the arrhythmia event. This segmentation allows the system to manage large ECG datasets by organizing them into meaningful, comparable segments rather than handling them as a single continuous stream.
2Measurement precision
If the device captures ECG data continuously for monitoring, then the measurement precision and detection capability improve, but the data overload increases
Solution Approach 1:
The system performs preliminary capture of the first ECG portion before the arrhythmia event occurs, establishing a baseline for comparison. This preliminary action ensures that accurate pre-event ECG data is available when arrhythmia occurs, enabling precise comparison without requiring continuous high-volume data capture during the critical event moment.
Solution Approach 2:
The configurable comparator module extracts and captures only the specific ECG portions that are most useful for arrhythmia detection and analysis - the pre-event baseline and the event期间的 data - rather than processing all continuous ECG data, thereby maintaining measurement precision while reducing data volume.
3Loss of information
If the wearable device stores all ECG data for comprehensive analysis, then the information available to healthcare professionals increases, but the loss of time for analysis increases
Solution Approach 1:
The patent extracts and stores only the most critical ECG portions for analysis - the first portion before arrhythmia and the second portion during arrhythmia - rather than storing all ECG data. This extraction approach provides healthcare professionals with the essential information needed for diagnosis while significantly reducing the time required to review and analyze the data.
Solution Approach 2:
By segmenting ECG data into distinct pre-event and during-event portions, the system enables rapid targeted analysis of only the relevant segments rather than requiring thorough review of continuous data streams, thus reducing analysis time while maintaining diagnostic completeness.
4Measurement precision
If the device captures and compares multiple ECG portions for arrhythmia detection, then the measurement precision improves, but the device complexity increases
Solution Approach 1:
The configurable comparator module is designed as a multi-functional unit that can capture, store, and compare different ECG portions based on configurable parameters. This universal module handles multiple tasks (pre-event capture, during-event capture, comparison, and display) through a single integrated system, improving arrhythmia detection accuracy without proportionally increasing overall device complexity.
