6-lead ECG Serial Analysis for Structural Heart Disease Validation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for diagnosing progressive structural heart disease using 12-lead electrocardiogram (ECG) data are resource-intensive and burdensome for patients, requiring multiple appointments and expensive equipment, with echocardiograms often needed for validation, which can be invasive and costly.
Innovation Solution
A system utilizing a 6-lead ECG to obtain and analyze ECG data at spaced intervals, allowing for serial analysis by a processor to validate signs of structural heart disease detected in 12-lead ECG data, reducing the need for resource-intensive tests and enabling home-based data collection with a less expensive and simpler device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If 12-lead ECG and echocardiogram are used for diagnosis, then diagnostic accuracy is improved, but resource consumption and patient burden increase
Solution Approach 1:
The diagnostic process is segmented into two phases: initial screening using 12-lead ECG with AI algorithm, and conditional follow-up using 6-lead ECG for serial monitoring. This segmentation allows accurate diagnosis to be achieved only when necessary, reducing overall resource consumption while maintaining diagnostic reliability.
Solution Approach 2:
A simplified 6-lead ECG device serves as an intermediary between the complex 12-lead ECG/echocardiogram system and home monitoring. This intermediary can perform serial analysis to validate disease progression, reducing the need for repeated expensive tests while maintaining diagnostic accuracy.
2Measurement precision
If 12-lead ECG is used for serial monitoring, then diagnostic precision is improved, but ease of operation and patient convenience deteriorate
Solution Approach 1:
The system uses a simpler, more portable 6-lead ECG device for serial monitoring instead of requiring the more complex 12-lead equipment. This cheaper, simpler device is sufficient for tracking disease progression over time, improving patient convenience while maintaining adequate measurement precision for validation purposes.
3Reliability
If echocardiogram is performed for validation, then diagnostic reliability is improved, but loss of time and cost increase
Solution Approach 1:
The system performs preliminary validation using 6-lead ECG serial analysis before requiring a full echocardiogram. By detecting disease progression trends through multiple 6-lead ECG measurements, the system can validate diagnoses without immediately resorting to time-consuming echocardiograms, reducing both time loss and costs while maintaining diagnostic reliability.
4Measurement precision
If multiple 12-lead ECG tests are performed, then measurement precision is improved, but loss of time and productivity increase
Solution Approach 1:
The system uses partial action by performing serial analysis with the simpler 6-lead ECG device rather than repeating the full 12-lead ECG. This partial approach (using fewer leads) is sufficient for tracking disease progression and validating diagnoses, improving medical resource efficiency while maintaining adequate measurement precision for the intended purpose.

AI summary
A system for diagnosing a progressive structural heart disease including a 6-lead electrocardiogram (ECG), a 12-lead ECG, and an analysis device. The analysis device including a processor configured to obtain 12-lead ECG data corresponding to a patient, analyze the 12-lead ECG data for signs of the progressive structural heart disease; based on the 12-lead ECG data indicating the disease: obtain multiple sets of 6-lead ECG data corresponding to the patient, the multiple sets of 6-lead ECG data being obtained during spaced apart time intervals to show changes over time; perform serial analysis on the multiple sets of the 6-lead ECG data to validate the indicated progressive structural heart disease; and control an operation of the detection device based on a result of the analysis.
