Solution Overview
Problem
Existing electrocardiogram analysis methods require repeated re-recording due to noise interference and electrode issues, and the second mode for selecting appropriate waveform segments is cumbersome and requires complex operations, especially for infrequent users.
Innovation Solution
An electrocardiogram analyzing apparatus and method that automatically extracts candidate segments from collected waveforms, excluding noise and including irregular heartbeats, and displays them for easy selection and analysis, allowing users to compare and record waveforms efficiently.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If automatic analysis is performed during real-time collection, then analysis speed is improved, but noise interference and electrode issues cause repeated re-recording reducing reliability
Solution Approach 1:
The system performs preliminary actions by automatically extracting multiple candidate waveform segments and preparing analysis results before the user needs to review them. The ECG analyzing apparatus extracts a plurality of candidate segments from collected waveforms, calculates analysis results for each candidate, and displays them in advance, so when the user views the results, the work is already completed and they only need to select from pre-prepared options.
2Reliability
If the user manually selects appropriate waveform segments for recording, then waveform quality is improved, but the operation becomes cumbersome and complex
Solution Approach 1:
The ECG analyzing apparatus performs self-service by automatically extracting multiple candidate waveform segments, calculating analysis results for each candidate, and displaying them with their analysis outcomes. The system serves itself by autonomously completing the waveform selection and analysis work that would otherwise require complex manual user operations, providing users with ready-to-select results.
Solution Approach 2:
The system performs preliminary actions by automatically extracting multiple candidate waveform segments and preparing analysis results before the user needs to review them. The ECG analyzing apparatus extracts a plurality of candidate segments from collected waveforms, calculates analysis results for each candidate, and displays them in advance, so when the user views the results, the work is already completed and they only need to select from pre-prepared options.
3Adaptability or versatility
If multiple waveform segments are displayed for selection, then user choice is improved, but display complexity increases
Solution Approach 1:
The display screen is segmented into distinct functional areas: a waveform display area showing multiple candidate waveform segments, and a separate analysis result display area showing the calculated results for each candidate. This segmentation allows the system to present multiple waveform options with their corresponding analysis results in an organized, non-overlapping manner that reduces display complexity while maintaining selection flexibility.
Solution Approach 2:
The system separates the display of waveform data and analysis results into different spatial dimensions or areas on the screen. By displaying waveforms in one area and their corresponding analysis results in another area, the system avoids cluttering a single space, thereby reducing perceived display complexity while still providing comprehensive information for multiple waveform candidates.

AI summary
Electrocardiographic waveforms for a plurality of candidate segments (analysis unit segments) are extracted from collected electrocardiographic waveforms and the extracted electrocardiographic waveforms for the plurality of candidate segments (analysis unit segments) are displayed on one screen. As a result, a user can determine, e.g., what candidate segment (analysis unit segment) analysis results to view while simultaneously viewing the electrocardiographic waveforms for the plurality of candidate segments (analysis unit segments) and which candidate segment to record, without any switching between screens, and as a result can perform appropriate electrocardiogram analysis using a simple operation.
