Solution Overview

Problem

In electrocardiogram measurements, it is challenging for interpreters to determine whether the electrodes were correctly attached during data collection, as existing systems do not provide clear indication of electrode attachment verification, potentially leading to unreliable waveforms due to mistaken attachments.

Innovation Solution

An electrocardiogram analysis apparatus with a mistaken attachment determining section that assesses electrode placement using input signals, displays a confirmation button if attachment is incorrect, and stores verification information to ensure accurate data interpretation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If measurement electrodes are automatically checked for mistaken attachment, then measurement reliability is improved, but information transparency for interpreters deteriorates

Engineering Contradiction:
Improvemeasurement reliabilityVSAvoidinformation transparency
Core Design Contradiction:
ReliabilityVSLoss of information

Solution Approach 1:

The system provides feedback to interpreters about electrode attachment status by storing and displaying information indicating whether measurement electrodes were checked for mistaken attachment. This feedback mechanism ensures interpreters are informed about the quality of the measured electrocardiogram data without compromising the automatic checking process.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The system performs preliminary checking of electrode attachment before final measurement completion. The mistaken attachment determining section checks electrode positions in advance, and the results are stored with the measurement data, allowing interpreters to review attachment status before making diagnostic decisions.

Inventive Principle:
Principle #10Preliminary action

2Measurement precision

If electrode attachment checking is performed, then measurement accuracy is improved, but system complexity increases

Engineering Contradiction:
Improveelectrode placement accuracyVSAvoidsystem complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The system performs self-checking of electrode attachment by automatically determining whether electrodes are mistakenly attached using the measured electrocardiogram signals themselves. This self-service approach eliminates the need for additional complex hardware or manual verification procedures.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent replaces manual electrode attachment verification with an automated signal-processing system. The mistaken attachment determining section uses electrocardiogram signal analysis to detect incorrect electrode placement, substituting mechanical/manual checking with electronic automation.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

AI summary

An electrocardiogram analysis apparatus includes: an electrocardiogram signal inputting section to which electrocardiogram signals of measurement electrodes attached to a subject are input; a mistaken attachment determining section which, by using the input electrocardiogram signals, determines whether the measurement electrodes are mistakenly attached or not; an outputting section which, if it is determined that the measurement electrodes are mistakenly attached, notifies of mistaken attachment of the measurement electrodes; and an electrocardiogram data storing section which, in a case where there is an input indicative of confirmation of the notification, stores information indicating that the measurement electrodes have been checked, together with the input electrocardiogram signals, and, in a case where there is not an input indicative of confirmation of the notification, stores information indicating that the measurement electrodes have not been checked, together with the input electrocardiogram signals.
