ECG Age Classification for Pediatric Diagnosis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ECG analysis systems often omit age information, leading to inaccurate diagnoses in both pediatric and adult patients, as ECG criteria vary significantly by age.
Innovation Solution
A method and system that analyze ECG inputs to determine whether a subject is pediatric or non-pediatric and classify them into appropriate age groups using trained machine learning or deep learning algorithms, even without provided age information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If automated ECG analysis software is used without age information, then analysis speed is improved, but diagnostic accuracy deteriorates
Solution Approach 1:
The system performs preliminary age estimation from ECG features before conducting the main diagnostic analysis. This preliminary action ensures that age-appropriate criteria are selected in advance, maintaining both fast automated processing and high diagnostic accuracy by pre-configuring the analysis parameters based on estimated patient age.
Solution Approach 2:
The ECG analysis system automatically estimates patient age from the ECG signal itself without requiring external age information. The system serves itself by extracting age-related features directly from the cardiac electrical activity, eliminating the need for manual age input while preserving diagnostic accuracy through age-stratified analysis criteria.
2Ease of operation
If age information is omitted from ECG analysis, then ease of operation is improved, but reliability of diagnosis deteriorates
Solution Approach 1:
The system automatically determines patient age from ECG features without requiring manual input or external documentation. This self-service approach maintains ease of operation by eliminating additional steps while ensuring reliability through age-appropriate diagnostic criteria that are automatically selected based on the estimated age from the ECG signal characteristics.
Solution Approach 2:
The system introduces an intermediary age estimation module that bridges the gap between ECG signal and diagnostic interpretation. This intermediary automatically infers age from cardiac electrical features and uses it to select appropriate diagnostic thresholds, thereby maintaining both operational simplicity and diagnostic reliability without direct age input.
3Measurement precision
If clinicians manually identify patient age in emergency situations, then diagnostic accuracy is improved, but time consumption increases
Solution Approach 1:
The system automatically extracts age information from ECG features without requiring clinician intervention or search for external records. This self-service capability maintains high diagnostic accuracy through age-stratified criteria while eliminating the time clinicians would spend manually identifying patient age, which is critical in emergency situations where every second counts.
Solution Approach 2:
The system performs age estimation as a preliminary step immediately upon receiving the ECG signal, before the clinician begins diagnostic interpretation. This preliminary action ensures age-appropriate criteria are ready in advance, maintaining diagnostic accuracy while saving valuable time by eliminating the need for subsequent manual age identification during the diagnostic process.

AI summary
A method for analysis of an ECG input for a subject to determine whether the subject is a pediatric subject or non-pediatric subject, and to classify the subject in one of a plurality of different age groups, comprising: receiving an ECG input for the subject; determining that the subject is a pediatric or non-pediatric subject; upon determining that the subject is a pediatric subject, determining that the subject belongs in one of a plurality of different pediatric age groups; upon determining that the subject is a non-pediatric subject, determining that the subject belongs in one of a plurality of different non-pediatric age groups; and performing an automated analysis of the received ECG input for the subject, wherein the automated analysis is based in part on the determined age group in which the subject belongs.
