ST-Segment Deviation Graphical Display for Clinical Trend Assessment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current patient monitors display ST-segment deviation values numerically, making it difficult for clinicians to quickly assess changes in a patient's condition over time and integrate information from multiple leads, especially in determining whether ischemia is worsening or improving.
Innovation Solution
Graphical representation of ST-segment deviations using bar graphs, plots, or line graphs that display both baseline and current values, with highlighting to distinguish between them and indicate trends, allowing for separate display of limb and precordial leads to facilitate quick evaluation of a patient's condition.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If ST-segment deviation values are displayed numerically, then the display is simple and compact, but it is difficult for clinicians to quickly assess changes in patient condition over time and integrate information from multiple leads
Solution Approach 1:
The patent transforms the one-dimensional numerical display of ST-segment deviation values into a two-dimensional graphical display. The graphical interface plots ST-segment deviation values against time, creating a visual trend line that allows clinicians to simultaneously view multiple leads and assess changes over time. This dimensional transformation resolves the contradiction by preserving the simplicity of numerical display while adding the trend visualization capability that was previously lost.
2Measurement precision
If multiple leads are displayed separately, then the information from each lead is clear and distinct, but the overall integration of information becomes complex and time-consuming
Solution Approach 1:
The patent merges the display of multiple leads into a single integrated graphical interface. Multiple lead traces are plotted simultaneously on the same graph with different visual identifiers, allowing clinicians to view and compare all leads in one unified display. This combining approach maintains the distinctness of individual lead data while eliminating the time required to separately evaluate each lead, thus resolving the contradiction between measurement precision and evaluation time.
3Measurement precision
If numerical values are used for ST-segment deviation, then the data is precise and easy to store, but the visual recognition of trends and patterns is difficult
Solution Approach 1:
The patent employs color coding and visual highlighting in the graphical display to enhance trend detection. Different colors represent different leads or time periods, and changes in color intensity or shading indicate the direction and magnitude of ST-segment deviation changes. This visual encoding preserves the precise numerical data while making trends and patterns immediately recognizable through color-based visual cues, thereby resolving the contradiction between measurement precision and trend detection difficulty.
