Computerized ECG Interpretation Visualization for Physician Understanding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Physicians rely on computerized electrocardiography (ECG) interpretation for clinical decisions but lack understanding of the basis for these interpretations, necessitating a system that makes CI understandable and actionable for independent diagnosis.
Innovation Solution
An ECG interpretation system with a display, user interface, processor, and memory that analyzes waveforms to calculate metrics, highlights segments, and generates textual information to categorize conditions, using colors and text to indicate condition types and statuses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If computerized interpretation is used to assist clinical decisions, then diagnostic efficiency is improved, but physician understanding of the interpretation basis deteriorates
Solution Approach 1:
The patent introduces an intermediary visualization layer between the computerized interpretation system and the physician. This layer includes graphical displays showing waveform segments, annotated ECG traces, and visual indicators that mediate the communication between the CI algorithm and the physician, making the interpretation basis visible and understandable while maintaining diagnostic efficiency
Solution Approach 2:
The patent replaces the traditional text-heavy or numerical-only presentation of ECG interpretation with a visual/graphical presentation system. By substituting mechanical information delivery methods with visual displays showing waveform segments, color-coded annotations, and graphical indicators, the system maintains automation benefits while improving physician comprehension of the interpretation basis
2Measurement precision
If detailed waveform analysis is performed to improve diagnosis accuracy, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the complex ECG waveform into distinct segments or regions of interest. Each segment can be independently analyzed and visualized, allowing detailed examination of specific features (such as P-wave, QRS complex, T-wave) without requiring the physician to analyze the entire waveform at once, thus maintaining diagnostic accuracy while managing system complexity
Solution Approach 2:
The patent extracts and highlights only the relevant waveform segments that are critical for diagnosis, separating them from the rest of the waveform. By taking out and emphasizing only the necessary portions (such as abnormal segments or key measurement points), the system achieves high measurement precision without requiring complex processing of the entire signal

AI summary
An electrocardiogram interpretation system includes a display and a user interface. A processor receives an ECG that includes a waveform of electrical activity of a patient's heart over a period of time and analyzes the waveform to calculate computerized interpretation metrics and detect at least one segment of the waveform corresponding to a behavior associated with a condition of the patient's heart and categorize a type of the condition and a status of the condition selected from a group including at least normal and abnormal with the computerized interpretation metrics. The processor generates, on the display, the waveform and highlight the at least one segment with a color selected from a plurality of colors, each color of the plurality of colors corresponding to the type of condition or the status of the condition. The processor generates, on the display, textual information that includes the type of condition or the status of the condition.
