Linear ECG Signal Display Using Cabrera Sequence
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing external defibrillators face challenges in accurately triaging patients with chest pain or acute coronary syndrome using 12-lead ECG waveforms, particularly for less-experienced clinicians, due to complex patterns and non-ACS conditions causing abnormal ST levels, leading to potential misdiagnosis and improper treatment.
Innovation Solution
The method involves receiving and processing ECG waveforms to determine specific data points, structuring them according to the Cabrera sequence, and displaying them on a linear scale with associated attributes and normal limits, allowing for intuitive and user-friendly interpretation of heart rhythm and potential STEMI conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional 12-lead ECG waveform display is used, then comprehensive cardiac monitoring is provided, but accurate triaging becomes difficult due to complex patterns and abnormal ST levels
Solution Approach 1:
The patent segments the ECG analysis by extracting and displaying individual data points (such as ST-segment measurements) separately from the complete waveform. Each data point is presented with its specific attribute and normal limits, allowing clinicians to focus on individual measurements without being overwhelmed by the complexity of the entire 12-lead ECG display.
Solution Approach 2:
The patent introduces an intermediary layer between the raw ECG waveforms and the diagnostic decision. This intermediary is represented by the structured data points that include measured values, attributes, and normal limits. This layer translates complex waveform patterns into simplified, actionable information that facilitates accurate triaging.
2Loss of information
If detailed ECG waveform analysis is provided, then diagnostic information is comprehensive, but ease of operation decreases for less-experienced clinicians
Solution Approach 1:
The patent divides the ECG analysis into discrete, manageable data points, each with its own attributes and normal limits. This segmentation allows less-experienced clinicians to process information in small, digestible units rather than attempting to interpret the entire complex waveform at once.
Solution Approach 2:
The patent transforms the continuous ECG waveform into discrete parameter measurements (data points) with associated attributes and normal limits. This parameter transformation makes the information more accessible and easier to interpret for clinicians of varying experience levels, as the structured format provides clear reference values for comparison.
3Productivity
If traditional ECG display methods are used, then waveform visualization is provided, but actionable information for treatment decisions is insufficient
Solution Approach 1:
The patent extracts key diagnostic information from the ECG waveforms and presents it as discrete data points with associated attributes and normal limits. This extraction process isolates the most actionable information (such as ST-segment measurements) from the background noise of the complete waveform, enabling rapid triaging decisions.
Solution Approach 2:
The patent incorporates normal limits as feedback references alongside each data point. This feedback mechanism allows clinicians to immediately compare measured values against established normal ranges, enabling rapid assessment of whether a finding is clinically significant and requiring further action or treatment intervention.
Data Source
AI summary
An illustrative method and system for displaying ECG data of a patient includes the steps of: receiving an ECG waveform of a patient, determining at least a first attribute of the ECG waveform, and determining at least one data point from the first attribute of the ECG waveform. The first data point and associated first attribute of the ECG waveform are displayed on a linear scale. In an alternative method, the at least one data point is structured in a database of ECG data according to the Cabrera sequence; the display domain of the display is divided into several recurrent display slots; and a sequential one of the several recurrent display slots is associated with the at least one data point, which is displayed on the linear scale in the order in which the at least one data point appears in the Cabrera structured database of ECG data.
