Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for detecting electrocardiogram (ECG) cable interchange are limited in their ability to accurately identify misconnections across different ECG lead systems, particularly in non-standard systems used in monitoring or exercise ECG devices, which can lead to erroneous waveforms and diagnostic reports.
Innovation Solution
An ECG controller that integrates with various ECG devices to detect and classify cable interchanges using a combination of waveform morphology and redundancy-based methods, employing an electrode interface, ECG interpreter, and cable interchange classifier to identify misconnections across standard and non-standard lead systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If morphology-based detection methods are used for ECG cable interchange detection, then detection capability is improved, but the method is limited to standard 12-lead systems and cannot accurately detect interchanges in non-standard lead systems
Solution Approach 1:
The patent implements a universal detection framework that adapts to multiple lead systems (standard 12-lead, Mason-Likar, reduced-lead) by configuring detection algorithms according to the specific lead system being used. The system maintains morphological analysis capabilities while adding system-specific adaptation layers that enable accurate cable interchange detection across different ECG configurations without requiring separate specialized systems for each lead type.
2Reliability
If redundancy-based detection methods are used, then detection robustness is improved, but computational complexity increases due to transformation and reconstruction operations
Solution Approach 1:
The patent applies partial redundancy analysis by selecting and analyzing only the critical lead combinations necessary for cable interchange detection rather than performing complete ECG reconstruction for all leads. The system identifies minimal sufficient subsets of leads that provide adequate redundancy for detection purposes, reducing computational burden while maintaining detection robustness through targeted analysis of key waveform relationships.
3Adaptability or versatility
If comprehensive detection algorithms are implemented for all lead systems, then detection coverage is improved, but processing time increases
Solution Approach 1:
The patent segments the cable interchange detection process into lead-system-specific modules, where each module is optimized for a particular lead system configuration (standard 12-lead, Mason-Likar, reduced-lead). The system first identifies the active lead system type and then activates only the corresponding detection module, avoiding the computational overhead of running comprehensive algorithms across all possible lead systems when only one configuration is present.

AI summary
An ECG controller for an ECG device is connectable to a base ECG lead system (e.g., a 12-lead system) whereby the ECG controller implements an ECG waveform morphology based and ECG lead redundancy based detection and classification of any cable interchange (e.g., a limb cable interchange or a precordial cable interchange) between the ECG controller and the base ECG lead system. Alternatively, the ECG controller is further connectable to a sub-base ECG lead system (e.g., a limb only-lead system or a limited precordial-lead system) whereby the ECG controller implements an ECG waveform morphology based detection and classification of any cable interchange (e.g., a limb cable interchange or a precordial cable interchange) between the electrode interface and the sub-base ECG lead system.
