ST Map for Cardiac Ischemia Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In urgent care settings, there is a risk of diagnostic error in interpreting electrocardiograms (ECGs) for cardiac ischemia due to misinterpretation by medical personnel, especially when ST segment changes are less definitive, leading to non-optimal patient treatment.
Innovation Solution
An electronic data processing device generates and displays an ST Map, superimposing an ischemia criteria area and highlighting the overlapping region between the ST area and the ischemia criteria area, enhancing visual detection of ischemia criteria satisfaction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If medical personnel interpret ECG using traditional methods, then diagnostic process is simple, but diagnostic accuracy decreases due to misinterpretation of ST segment changes
Solution Approach 1:
The patent introduces an intermediary computational system that processes ECG data and generates visual maps representing ischemia criteria. This mediator translates complex electrical signals into intuitive graphical representations, allowing medical personnel to diagnose ischemia accurately without needing to manually interpret complex ST segment changes.
Solution Approach 2:
The patent creates disposable or easily regeneratable visual representations (maps) of ischemia criteria that can be quickly generated from ECG data. These visual maps serve as single-use diagnostic aids that simplify the interpretation process while maintaining high diagnostic accuracy.
2Measurement precision
If medical personnel carefully analyze ECG to improve diagnostic accuracy, then diagnostic precision increases, but time required for diagnosis increases
Solution Approach 1:
The patent performs preliminary computational processing of ECG data to pre-calculate and visualize ischemia criteria before clinical interpretation is needed. The system pre-processes the electrical signals into meaningful visual maps that highlight relevant diagnostic features, eliminating the need for time-consuming manual analysis while preserving diagnostic accuracy.
Solution Approach 2:
The patent uses color-coded visual representations to encode diagnostic information in the ECG data. Different colors represent different levels or types of ischemia criteria satisfaction, allowing medical personnel to quickly assess diagnostic status at a glance without needing to measure or calculate values manually.
3Reliability
If traditional ECG interpretation methods are used, then equipment complexity is low, but reliability of ischemia detection decreases due to human error
Solution Approach 1:
The patent enables the ECG system to self-evaluate ischemia criteria through automated computational processing. The system independently calculates whether ischemia criteria are satisfied based on the recorded electrical signals, reducing reliance on human interpretation and thereby improving detection reliability while managing system complexity through software-based solutions.

AI summary
Disclosed herein are methods and systems providing improvements enhancing speed and accuracy in interpreting the electrocardiogram (ECG) for ischemia identification using a graphical presentation. An ischemia criteria and ST segment measurements to be tested are graphically presented simultaneously. The graphical presentation allows the violation of the ischemia criteria to be visualized without any ambiguity. To further ensure that such a condition will not be overlooked, additional graphical highlighting is provided. This graphical approach can be used to improve the detection of conditions that fulfill the specified ischemia criteria and reduce the variation of individual interpretation for patients with border-line ST segment changes.
