Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current ECG devices lack the ability to display ECG leads with appropriate resolution and calibration, making it difficult for users to diagnose conditions effectively, and printed strips are prone to loss or damage, limiting their usability.
Innovation Solution
A system that digitally renders ECG waveforms with variable resolution and a grid for calibrated time and amplitude measurements on an electronic display, allowing users to select and highlight features for explanation, providing labels and annotations to clarify interpretation statements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If strip chart printers are used to display ECG leads, then ECG waveforms can be printed and recorded, but the printed strips can be easily lost or damaged and the print area is limited
Solution Approach 1:
The patent replaces physical printed strips with digital copies displayed on electronic screens. The ECG waveforms are rendered as digital images that can be displayed at various resolutions and zoomed in without losing quality, eliminating the limitations of physical print area and durability while maintaining the diagnostic functionality.
Solution Approach 2:
The patent substitutes the mechanical strip chart printing system with an electronic display system. Instead of using physical paper and printers, the ECG leads are displayed digitally on screens, allowing for unlimited display area, no physical damage, and the ability to adjust resolution and magnification dynamically.
2Adaptability or versatility
If standard digital displays are used for ECG waveforms, then ECG can be displayed digitally, but the resolution and calibration grid are insufficient for diagnostic measurements
Solution Approach 1:
The patent implements dynamic resolution adjustment where the display can be zoomed in and out, and the rendering resolution can be changed based on diagnostic needs. The system adapts the display parameters (magnification, resolution, grid calibration) dynamically to provide both overview and detailed measurement capabilities, transforming a static display into a versatile diagnostic tool.
Solution Approach 2:
The patent changes key display parameters including resolution, magnification, and grid calibration to optimize for different diagnostic scenarios. The system allows adjustment of these parameters to achieve the appropriate measurement precision for various ECG analysis tasks, transforming the display from a fixed-resolution medium to an adaptable measurement tool.
3Productivity
If ECG interpretation statements are provided without visual references, then interpretation can be generated quickly, but users cannot clearly understand the reasons for each interpretation element
Solution Approach 1:
The patent introduces visual annotations and highlighted regions on the ECG waveform as an intermediary between the interpretation text and the actual ECG data. These visual elements serve as mediators that connect the textual interpretation statements with their corresponding waveform features, providing clear visual references that explain the reasoning behind each interpretation element without slowing down the generation process.
Solution Approach 2:
The patent replaces traditional text-only interpretation with a integrated visual-digital system that combines interpretation statements with graphical annotations. Instead of relying solely on textual descriptions, the system uses digital rendering to overlay visual markers, highlights, and references on the waveform, making the interpretation reasoning transparent and easily understandable.

AI summary
A system for electrocardiogram (ECG) interpretation includes a processor and memory coupled to the processor. A rendering module is stored in the memory and is configured to receive input from an ECG and correlate interpretation statements with ECG measurements responsible for the interpretation statements in the ECG. An interface is configured to permit user selection of at least one interpretation statement in a display, the display being configured to render visual indications of the ECG measurements on digitally rendered waveforms of the ECG.
