ECG ST-Amplitude Display by Heart Region for Faster Triage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional electrocardiogram (ECG) methods require professional interpretation to determine heart abnormalities, leading to prolonged decision-making for treatment, which is inefficient in emergency situations.
Innovation Solution
An electrocardiogram display method that classifies ECG signals into distinct heart regions, uses bar charts with abnormal threshold lines, and provides alerts for abnormal amplitudes, allowing quick identification of heart damage locations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional ECG interpretation methods are used, then professional medical personnel can accurately determine heart abnormalities, but the diagnosis and treatment time is prolonged
Solution Approach 1:
The patent segments the ECG analysis by dividing leads into three distinct groups (anterior, inferior, lateral) based on their anatomical orientation. Each group is visually separated and labeled, allowing medical personnel to quickly locate and assess specific heart regions without analyzing all leads sequentially, thus reducing diagnosis time while maintaining accuracy
Solution Approach 2:
The patent uses color-coded threshold lines (red for upper thresholds, purple for lower thresholds) to visually indicate abnormal ST amplitude ranges. This color-coding system enables rapid visual detection of abnormalities without requiring detailed numerical analysis, significantly speeding up the diagnostic process while preserving measurement precision
2Measurement precision
If detailed ECG analysis is performed, then accurate heart abnormality location is determined, but the complexity of the display increases
Solution Approach 1:
The patent simplifies display complexity by segmenting leads into three anatomically-based groups (anterior, inferior, lateral) with clear visual separation. This organizational structure maintains precise location information while presenting it in a structured, easy-to-navigate format that reduces perceived complexity
Solution Approach 2:
The patent applies local quality by providing detailed information (ST amplitudes, threshold lines) specifically at the locations where it is most needed - within each lead's bar chart. This targeted approach maintains analytical precision without requiring complex global display mechanisms, as each local area contains only the relevant information for that heart region

AI summary
An electrocardiogram display method includes the following steps. First, the electrocardiogram is measured, the ST amplitudes of multiple electrocardiogram leads are then calculated based on the measured electrocardiogram, the measured electrocardiograms are classified according to regions of the heart, and bar charts of the ST amplitudes of the electrocardiogram leads are drawn according to the region classification.
